The AAK Glossary

Development(al) refers to the steps or stages in the growth of a child.

Developmental delay is an expression that is used to describe a child who is behind in at least one area of development, including physical, cognitive, communicative, social-emotional and/or adaptive functioning. It specifically refers to development which does not occur within expected time ranges.

Developmental history involves information based on the reporting of the developmental progress of a child in skills such as, sitting, crawling, standing, walking, or talking.

Developmental language delay is characterized by a slow development of language in preschoolers.

Developmental milestones refer to the age, or age range, at which an infant or toddler normally develops a particular skill. For example, by nine months, a child should be able to grasp and toss a bottle. Skills such as taking a first step, smiling for the first time, and waving "bye-bye" are considered developmental milestones. Children reach milestones in how they play, learn, speak, behave, and move.

Developmental tests are assessments that will indicate if a child has not realized the expected level of development based on his or her age group.

Diagnosis refers to the process of identifying a condition by its signs, symptoms, and from the results of various diagnostic procedures. The term "diagnostic criteria" is the combination of signs, symptoms, and test results that allows a doctor or other qualified personnel to ascertain the diagnosis of the respective condition.

Direct Instruction or DI refers to a rigorously developed, highly scripted method of teaching that is fast-paced and provides constant interaction between students and the teacher. Direct instruction emphasizes well-developed and carefully planned lessons that are designed around small learning increments with clearly defined and prescribed teaching tasks.

Disability refers to a physical, sensory, cognitive or affective impairment that causes a student to need special education.

Discrete Trial Teaching or DTT involves skills that are broken down into smaller tasks and presented in trials. Trials are discrete in that they have a very clear beginning, middle and end. Discrete trial teaching is primarily taught on a one-to-one basis and allows for many opportunities to respond, practice, and earn reinforcement. In discrete trial teaching, data are collected on each trial and visual displays are used to monitor progress.

Disorder refers to a mental or physical condition in which there is a disturbance of normal functioning.

Early Intervention Official Designee or EIOD is the person who serves as the "single point of entry" for the Early Intervention Program or EIP. Every county in NYS, including New York City, has an Early Intervention Official Designee or EIOD who is responsible for making sure that eligible children receive evaluations at no cost. The EIOD is also responsible for choosing an initial service coordinator to help families arrange for their child's evaluations and assist with the Individualized Family Service Plan.

Early Intervention Program or EIP is a statewide program that provides many different types of services to infants and toddlers, from birth to 3 years old, and their families, who meet the eligibility requirements for Early Intervention. In New York State, the Department of Health is the lead state agency responsible for the Early Intervention Program.

Early Intervention services are those provided by qualified personnel that meet the needs of the child and family as described in the Individualized Family Service Plan or IFSP. These services are provided with parental consent and to the maximum extent possible in the child's natural environment.

Educational Psychologist refers to a psychologist who specializes in learning and in the behavioral, social, and emotional problems that interfere with school performance.

Eligibility or Eligibility requirements in general are requirements that a child must meet in order to receive services. This will include the age of the child and whether or not the child has a disability or developmental delay.

Eligibility requirements for the Committee on Preschool Special Education refers to children 2 years and nine months (2.9) through 5 years of age who exhibit a significant delay or disability in one or more functional areas of development related to cognitive, language, communication, adaptive behavior, social and emotional or motor development which adversely affect the child's ability to learn. Eligibility for Preschool Special Education Services is based upon the determination of the CPSE.

Eligibility requirements for the Committee on Special Education refers to students 5 years through 21 years of age, who, because of mental, physical or emotional reasons, have been identified as having a disability and who require special services and programs approved by the Department of Special education.

Eligibility requirements for the Early Intervention Program refers to children who are in need of support from birth to 3 years of age who have a confirmed disability or established developmental delay.

Errorless teaching refers to an instructional strategy that ensures a child always responds correctly. Following an instruction, a child is provided with the immediate correct response to that instruction. This prevents any chance for an incorrect response. No opportunities for mistakes are allowed. Prompts are systematically removed until a child is able to respond correctly on their own.

Evaluation refers to the use of various assessment methods to determine if an individual meets the eligibility requirements for special education services.

Evaluation process refers to when evaluations are arranged in order to formally assess an individual's abilities and needs.

Expressive language refers to the process of formulating and sending a message. One way to express language is through speech or sign language. Others may include Augmentative Communication Devices or ACD's, like pointing to words and pictures on a communication board (ex: PECS), or formulating written messages on a computer screen.

Extended school day refers to a provision for special education students to receive instruction for a period longer than the standard school day. This sometimes includes "double" kindergarten, later afternoons, or earlier starting times.

Extended school year refers to a provision for a special education student to receive instruction during ordinary school "vacation" periods.

Family assessment is the process used to identify and collect information related to the family concerns, priorities, and resources.

Feeding problems can be defined as the inability or refusal to eat certain foods because of oral-motor, sensory, positioning, and/or behavioral issues.

Feeding therapy involves the assessment and management of individuals with swallowing and feeding disorders. The speech-language pathologist is the primary qualified personnel involved in this type of therapy. In addition to performing a clinical swallowing and feeding evaluation and instrumental assessments of swallowing function, with medical professionals, as appropriate, identification of normal and abnormal swallowing structures and functions can be identified.

Fine motor function refers to the development of skills involving the smaller muscle groups or those skills which require tiny muscle movements. For example, writing or typing would require fine motor movement.

Fine motor skills include the ability to manipulate small objects, transfer objects from hand to hand, and various hand-eye coordination tasks. Fine motor skills may involve the use of very precise motor movement in order to achieve an especially delicate task. Some examples of fine motor skills are using the pincer grasp (thumb and forefinger) to pick up small objects, cutting, coloring, writing, or threading beads.

Fluency refers to the ability to express oneself readily, clearly and effectively. It is characterized by speech that is relatively smooth in rate and rhythm. It is free of interruptions such as fillers and repetitions.

Formal assessment refers to an evaluation of a student's needs using standardized tests and other tools. A team of qualified personnel uses the assessment to determine a child's eligibility for special education and related services.

Functional behavioral assessment is the process used to determine why a student engages in behaviors that impede learning and how the student's behavior relates to the environment. The functional behavioral assessment shall include, but is not limited to, the identification of the problem behavior, the definition of the behavior in observable and measurable terms, and the identification of the contextual factors that contribute to the behavior. From this assessment, a hypothesis is developed regarding the general conditions under which the behavior occurs and the probable consequences that serve to maintain it.

Functional capabilities, with regard to individuals with disabilities, refer to being able to accomplish daily living tasks, communicate, learn, work, and participate in recreation activities. The goal of maximizing the functional capabilities of an individual is for that individual to be able to achieve greater independence and to enhance his or her quality of life.

Functional evaluation involves the assessment of the functional capabilities of an individual with a disability to determine whether or not that individual could benefit from the use of an assistive technology device and the support of assistive technology services.

Generalization of skills refers to the extent to which a student successfully and effectively applies a skill outside the setting in which it was learned. This term usually refers to the ability to demonstrate skills with different people, across different situations, settings, and time.

Generalization procedures are those procedures used to ensure that learned responses or skills can be used broadly. The goal of generalization procedures is to promote the generalization of skills.

Gross motor functions are those which require large muscle movements. For example, walking or jumping would require gross motor movement. Gross motor development usually follows a pattern. Generally large muscles develop before smaller ones; thus, gross motor development is the foundation for developing skills in other areas, such as, fine motor skills. Development also generally moves from top to bottom. The first thing a baby usually learns to control is its eyes.

Group developmental intervention or Developmental toddler groups refer to Early Intervention services delivered to a group of eligible children at an Early Intervention site or community-based setting. These groups may be large or small and may include children without disabilities. The goal of these groups is to provide multifaceted learning experiences and opportunities adapted to the special needs of the children in the group. Attendance can be up to five, two and a half hour sessions.

Hearing impairment refers to permanent or fluctuating impairment in hearing that adversely affects educational performance.

Independent Educational Evaluation or IEE means that a parent has the right to obtain an "outside evaluation" such as a procedure, test or assessment done by a qualified personnel who does not work for the school district or other public agency responsible for the child's education. This evaluation can be at public expense if the parent disagrees with the evaluation obtained by the school.

Individualized Educational Plan or IEP refers to the document developed at an IEP meeting which sets the standard by which subsequent special education services are usually determined appropriate. It is a written statement, developed, reviewed, and revised, that includes the components to be provided and the annual goals to meet the unique educational needs of a student with a disability.

Individualized Educational Program Meeting or IEP meeting refers to a gathering required, at least annually by the Committee on Pre-school Special Education (for students 2.9 to 5 years old) or Committee on Special Education (for students 5 to 21 years old), under the Individuals with Disabilities Education Act or IDEA in which an Individualized Educational Plan or IEP is developed for a student, where appropriate, in need of, or receiving, special education.

Individual Family Service Plan or IFSP is the document which outlines the services to be delivered to families of infants and toddlers under the age of 3 years, with disabilities, who are eligible to receive special services through the Early Intervention Program. The IFSP must be based on the child's evaluations and assessments and describe who will be providing services, where they will be provided, how often, and for how long. A Service Coordinator is responsible for development and coordination of the IFSP services.

Individualized Family Service Plan or IFSP meeting refers to a gathering where the IFSP is developed jointly by the family and appropriate qualified personnel involved in the provision of Early Intervention Services. The IFSP will be reviewed every six months, or sooner if you request it, to evaluate your child's progress and continued need for services. You will be given a copy of your IFSP each time that it is written or changed by you and your team.

It addresses the educational needs of children with disabilities from birth to 21 years of age.

Infants and toddlers refer to children not yet three years of age.

Language development is the process by which children come to understand and communicate language during early childhood. Language refers to the exchanging of ideas from one person to another. Language can be conveyed through written and verbal expression. Some nonverbal means of communication could be through art, facial expression, eye contact, body language, and vocalizations.

Language disorder refers to impairment in the ability to understand and/or use words in context, both verbally and nonverbally. Some characteristics of language disorders include improper use of words and their meanings, inability to express ideas, inappropriate grammatical patterns, reduced vocabulary and inability to follow directions. One or a combination of these characteristics may occur in children who are affected by a language learning disability or developmental language delay. Children may hear or see a word but not be able to understand its meaning. They may have trouble getting others to understand what they are trying to communicate.

Learned response refers to that which has been taught. The response may be learned through intentional teaching, or may be learned through interaction with the environment.

Learning Disability or LD refers to a neurobiological disorder that affects the way an individual receives, processes, or expresses information and impairs his or her ability to read, write, or do math.

Least Restrictive Environment or LRE means that, whenever possible, special education services must be provided in a general education setting rather than in separate classes or schools. The educational environment must provide the special education student with the special education and related services needed, to the maximum extent appropriate, with other students who do not have disabilities. Also, these services must be provided as close as possible to the student's home.

Legal guardian refers to any person who can make legal decisions for a minor child.

Literacy Specialists work closely with students to help them work toward achieving reading skills that match their current grade level. Literacy specialists, sometimes called reading specialists, strive to increase the reading capabilities of all students through individualized and school-wide reading programs. By using literacy materials and resources, a diverse set of strategies and methods, and ongoing collaboration with classroom teachers, parents and administrators, literacy specialists support learning to read and comprehend meaning from printed words. Literacy specialists may conduct assessments, create individualized reading plans to match student ability and/or learning style, consult with parents and teachers to recommend at-home strategies for reading skill improvement, and may coordinate school-wide reading intervention and literacy programs.

Management involves using the information obtained from an assessment to plan, organize, access, implement, and direct efforts for the purpose of accomplishing a goal.

Modification of services refers to the alteration, change, or adjustment of special education services.

Motor planning requires that, when presented with a given a task, an individual demonstrates the ability to develop an idea, organize, and utilize the materials needed, and then sequence the steps necessary to complete the task. Individuals who exhibit poor motor planning may seem accident prone. They often struggle to master new skills because they have difficulty sequencing the steps needed to move and perform effectively.

Motor skills refer to a learned series of movements that combine to produce a smooth, efficient action. Both fine motor and gross motor skills are involved in purposeful movement.

Occupational therapists can work on improving underlying sensory motor foundation skills, fine motor coordination, visual motor control, visual perception and activities of daily living.

Occupational therapy or OT services are related services associated with self-help skills, adaptive behavior, play, sensory motor, and postural development. Occupational therapy services involve a functional evaluation of the student and the planning and use of a program of purposeful activities to develop or maintain adaptive skills. Occupational therapy services are designed to help individuals with disabilities achieve maximal functional capability in their daily life tasks.

Operant conditioning is the use of consequences to modify the occurrence and form of behavior. Operant conditioning deals with the modification of "voluntary behavior" or operant behavior. Operant behavior "operates" on the environment and is maintained by its consequences.

Oral-motor function refers to the use of the muscles in and around the face during speech and feeding. This includes the coordination, range of motion, and strength of the lips, tongue, palate, jaw, and teeth.

Outcomes are the statements of changes that parents wish to see in their child or family. These statements are a part of the Individualized Family Service Plan or IFSP and, for older students, are an important consideration when developing the annual goals for the Individualized Education Program or IEP.

Parent and child groups are Early Intervention Services that are delivered to a group of parents and children together by one or more qualified personnel at an Early Intervention Site or community-based setting. The primary goal is to help parents generalize skills that children learn to home and other natural settings.

Parent counseling and family training involves assisting parents, family and caregivers in understanding the special needs of their child. This includes providing information about child development, the understanding of and working with a child with a disability, and helping to facilitate the necessary skills that will allow for support of the goals of their child's educational program.

Pervasive Developmental Disorder, Not Otherwise Specified or PDD-NOS is a diagnostic condition in which some, but not all, features of Autism or another explicitly identified condition in the category of Pervasive Developmental Disorders or PDD are identified.

Pervasive Developmental Disorder or PDD refers to a group of five disorders characterized by delays in the development of multiple basic functions including socialization and communication. The pervasive developmental disorders are: Autism, the most commonly known Rett Syndrome, Childhood Disintegrative Disorder, Asperger's Syndrome, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS), which includes atypical Autism.

PROMPT stands for Prompts for Restructuring Oral Muscular Phonetic Targets. It is a speech and language treatment technique allowing a trained therapist, during communicative exchange, to physically manipulate a child's jaw, face and mouth to show how a speech sound, sounds in words, or words in sentences are produced. The PROMPT approach holds the belief that communication (verbal or not) represents the integration of a child's mental, physical, and emotional development. A breakdown in any of these developmental areas can lead to communication difficulties. When a child's speech and language needs are analyzed and treated by a PROMPT-trained therapist, he/she will also incorporate activities that address areas of developmental needs including cognitive function and social skills. The goal of PROMPT therapy is to achieve a state of equilibrium across these developmental areas to the highest level attainable by that child.

Psychological evaluation means a process by which a New York State certified school psychologist or licensed psychologist uses, to the extent deemed necessary for purposes of educational planning, a variety of psychological and educational techniques and examinations in the student's native language to study and describe a student's development, learning ability, behavior, and other personality characteristics.

Sensory Integration Dysfunction or Sensory Impairment is considered a neurological disorder that results from the brain's inability to integrate certain information received from the body's five basic sensory systems. These sensory systems are responsible for detecting sights, sounds, smell, tastes, temperatures, pain, and the position and movements of the body. The brain then forms a combined picture of this information in order for the body to make sense of its surroundings and react to them appropriately. The ongoing relationship between behavior and brain functioning is called Sensory Integration or SI. Sensory integration provides a crucial foundation for later, more complex learning and behavior.

Sensory integration gym refers to a facility that is designed to provide therapeutic intervention to students who have sensory integration dysfunction or sensory impairment.

Sensory motor foundation skills rely on the interaction of sensation and movement. We receive sensory information from our bodies and the environment through our senses. This sensory information then needs to be organized and processed in order to be able to produce an appropriate motor or movement response that makes it possible to be successful in our daily tasks.

Service Coordinator refers to a person who works in partnership with the family of an infant or toddler with a disability to provide support and services that help the family to coordinate and obtain their rights under the Early Intervention Program or EIP and services agreed upon in the Individualized Family Service Plan.

Social and emotional development and social interaction skills involve relating to others. This area emphasizes many skills that increase self-awareness and self-regulation. Research shows that social skills and emotional development (reflected in the ability to pay attention, make transitions from one activity to another, and cooperate with others) are a very important part of school readiness.

Social history means a report of information gathered and prepared by qualified professionals pertaining to the interpersonal, familial, and environmental variables which influence a student's general adaptation to school, including but not limited to, data on family composition, family history, and developmental history of the student, health of the student, family interaction, and school adjustment of the student.

Speech and language therapy may include, depending upon the nature and severity of the disorder, common treatments that range from physical strengthening exercises, instructive or repetitive practice and drilling, to the use of audio-visual aids and introduction of strategies to facilitate functional communication. Speech and language therapy may also include sign language and the use of picture symbols or Augmentative Communication Devices or ACD's.

Stages of development refer to building on the successful completion of earlier stages of development. Challenges in development involve those stages not successfully attained by an expected age.

Student with a disability means a student with a disability who has not attained the age of 21 prior to September 1st and who is entitled to attend public schools and who, because of mental, physical, or emotional reasons, has been identified as having a disability thus requiring special education services and programs approved by the Department of Education.

Swallowing disorder or dysphagia is a condition that suggests difficulty in the passage of solids or liquids from the mouth to the stomach.

Tourette Syndrome or TS is a neurobiological disorder characterized by repetitive, stereotyped, involuntary movements and vocalizations called tics. The early symptoms are almost always noticed first in childhood, with the average onset between the ages of 7 and 10 years. Although Tourette Syndrome can be a chronic condition with symptoms lasting a lifetime, most people with this condition experience their worst symptoms in their early teens, with improvement occurring in their late teens and continuing into adulthood.

Transition planning is a process to help children who are approximately age 3 years of age, transition out of the Early Intervention Program by determining the child's needs for educational planning at the preschool level.

Transition services mean a coordinated set of activities for a student with a disability, to facilitate the student's movement from home to an educational environment or from one educational environment to another. The coordinated set of activities must be based on the individual student's needs and take into account strengths, preferences and, where appropriate, individual interests.

Twelve-month special service means a special education service and/or program provided on a year-round basis for students determined to be eligible and whose disabilities require a structured learning environment of up to 12 months duration to prevent substantial regression.

Verbal Behavior or VB is the behavioral analytic approach to analyzing, teaching, and understanding language as theorized by B.F Skinner. Verbal behavior theory explains language as it would any other observable behavior; as such, it is subject to the same principles that govern all behavior. It focuses on teaching verbal behaviors (language skills) through a collection of highly effective teaching procedures taken from the science of behavior analysis. VB has been successfully used to teach functional communication to individuals with Autism Spectrum Disorders or ASD and other developmental disabilities. In Verbal behavior, all aspects of functional communication are divided into smaller teachable components that utilize motivation and reinforcement to teach echoics, mands, and tacts, intra-verbal and other more complex verbal operants.
