The words, in plain language.

Every world has its jargon, and this one has more than most. Here are the acronyms and terms you'll meet across school, medical, therapy, and sensory care, in plain language. It's a starting point to help you follow the conversation and ask good questions, not a diagnosis or legal advice. Your child's team can tell you how each term applies to them.

School, IEP & rights

IEP
Individualized Education Program
A written plan for a student who qualifies for special education. It lays out your child's goals, the services and supports they'll receive, and how progress is measured. Reviewed at least once a year.
504 Plan
Section 504
A plan that provides accommodations for a student with a disability who doesn't need specialized instruction. Lighter-touch than an IEP: think extra time or preferential seating rather than specialized teaching.
IDEA
Individuals with Disabilities Education Act
The federal law that guarantees eligible children a free, appropriate public education and the right to an IEP.
FAPE
Free Appropriate Public Education
Your child's right, under IDEA, to an education that meets their needs at no cost to you.
LRE
Least Restrictive Environment
The principle that children should learn alongside peers without disabilities as much as is appropriate for them.
Present Levels
PLAAFP
Present Levels of Academic Achievement and Functional Performance: the part of the IEP describing how your child is doing right now. Everything else in the plan builds on it.
Goals
The specific, measurable skills the team expects your child to work toward over the year, each with a starting point and a target.
Accommodations
Changes to how your child learns or shows what they know, without changing what they're expected to learn (extra time, a quiet room, text read aloud).
Modifications
Changes to what your child is expected to learn, such as fewer or different objectives. Different from accommodations.
Related Services
Support services that help your child access their education: speech, occupational, or physical therapy, counseling, or transportation.
Resource / Resource Room
A separate setting where a special education teacher gives targeted help, usually for part of the day.
Pull-out services
Support delivered by taking your child out of the regular classroom for a time, such as to a resource room or therapy.
Push-in services
Support delivered inside the regular classroom, where the specialist comes to your child.
Inclusion
also: Mainstreaming
Educating children with disabilities in the general classroom alongside their peers, with supports in place.
Service minutes
The exact amount of each service your child receives (for example, 30 minutes, twice a week). Worth getting in writing.
Paraprofessional
Para / Aide
A trained classroom assistant who supports a student or small group, sometimes one-on-one.
Evaluation
Eval
The testing and observation used to decide whether your child qualifies for services and what they need. You can request one in writing.
IEE
Independent Educational Evaluation
An outside evaluation you can request, often at public expense, if you disagree with the school's evaluation.
Prior Written Notice
PWN
A formal written notice the school must give you before it changes, or refuses to change, your child's identification, evaluation, or placement.
Eligibility
Whether your child qualifies for special education under one of IDEA's categories.
ESY
Extended School Year
Special education services provided beyond the normal school year, such as over the summer, when needed to prevent loss of skills.
Transition Plan
The part of the IEP, starting in the teen years, that plans for life after high school: work, further education, and independent living.
FBA
Functional Behavior Assessment
A look at why a behavior is happening, what sets it off, and what it accomplishes, used to build the right support.
BIP
Behavior Intervention Plan
A written plan, often built from an FBA, for preventing and responding to a specific behavior.
MTSS / RTI
Multi-Tiered System of Supports
A tiered way schools give increasing levels of extra help and track progress, often before or alongside special education.
Due Process
A formal route to resolve disagreements with the school about your child's services.
Mediation
A voluntary, less formal way to resolve disagreements with the school, with a neutral third party.
Early Intervention
EI
Services for babies and toddlers, birth to three, with delays or disabilities.
IFSP
Individualized Family Service Plan
The early-intervention version of an IEP, for children under three, centered on the whole family.

Diagnoses & profiles

ASD
Autism Spectrum Disorder
A developmental difference affecting communication, social interaction, and sensory experience, with a wide range of strengths and needs.
ASD Levels
Levels 1-3
Autism is described in three levels based on how much daily support a person needs, Level 1 the least and Level 3 the most. Levels can shift with context and over time.
ADHD
Attention-Deficit/Hyperactivity Disorder
A difference in attention, impulse control, and activity level.
CAS
Childhood Apraxia of Speech
A motor speech disorder where the brain has trouble coordinating the precise mouth movements for speech, even when your child knows exactly what they want to say.
SPD
Sensory Processing Disorder
Difficulty taking in and responding to everyday sensory information like sounds, textures, and movement, which can lead to feeling overwhelmed or under-responsive.
ARFID
Avoidant/Restrictive Food Intake Disorder
A feeding disorder where eating is limited by sensory aversions, low appetite or interest, or fear of choking or vomiting, rather than by body-image concerns. It can affect growth and nutrition.
Dyslexia
A learning difference that mainly affects reading and spelling.
Dysgraphia
A learning difference that affects writing: handwriting, spelling, and putting thoughts on paper.
Dyscalculia
A learning difference that affects working with numbers and math.
Developmental Delay
DD
When a child reaches developmental milestones later than typical. “Global” means delays across several areas at once.
Intellectual Disability
ID
Differences in reasoning, learning, and everyday skills that begin in childhood.
Gestalt Language Processing
GLP
A way of learning language in whole chunks, or “gestalts” (like a memorized phrase), before breaking them into single words. Common in many autistic children.
Echolalia
Repeating words or phrases heard from people or media. It often carries meaning and can be part of gestalt language development.
Hypotonia
Low muscle tone, which can make movement, posture, and coordination harder.
Neurodivergent
Neurodiversity
The idea that brains naturally vary. “Neurodivergent” describes a brain that works differently from what's considered typical, such as autism or ADHD.

Therapies & providers

ABA
Applied Behavior Analysis
A therapy approach that uses learning principles to build skills and support behavior. Common in autism care and sometimes debated, so it's worth understanding the specific approach your provider takes.
BCBA
Board Certified Behavior Analyst
A graduate-level professional who designs and oversees ABA programs and supervises RBTs.
RBT
Registered Behavior Technician
A trained paraprofessional who delivers ABA day-to-day under a BCBA's supervision.
SLP
Speech-Language Pathologist
Your speech therapist. Works on communication: speech sounds, language, social communication, and sometimes feeding and swallowing.
OT
Occupational Therapist
Helps with the “occupations” of childhood: fine motor skills, self-care, handwriting, and sensory needs.
PT
Physical Therapist
Helps with gross motor skills, strength, balance, and movement.
AAC
Augmentative and Alternative Communication
Tools and methods that support or replace speech, from picture boards to speech-generating apps and devices.
Feeding therapy
Therapy, often from an OT or SLP, that helps children who struggle with eating, including sensory and motor feeding challenges.
Developmental Pediatrician
A pediatrician with extra training in evaluating and supporting developmental and behavioral differences. Often the quarterback of your child's care team: helping coordinate the specialists, therapies, and the big-picture plan so it works as one.

Sensory & the body

Sensory processing
How the brain takes in and organizes information from the senses in order to respond to the world.
Interoception
The sense of what's happening inside the body: hunger, thirst, needing the bathroom, tiredness, and even emotions.
Proprioception
The sense of where your body is in space, from receptors in the muscles and joints. It supports coordination and feeling grounded.
Vestibular sense
The balance-and-movement sense, based in the inner ear. It tells the body about motion, head position, and gravity.
Sensory diet
A personalized set of sensory activities (movement, deep pressure, quiet) that helps a child stay regulated through the day. Designed with an OT.
Stimming
Self-stimulatory behavior such as rocking, flapping, or repeating sounds, which can help with regulation, focus, or expressing feeling.

Helpful concepts

Self-regulation
The ability to manage one's own emotions, energy, and attention.
Co-regulation
Calming with the help of a trusted adult's steady presence. It comes before, and builds toward, self-regulation.
Meltdown
An intense response to feeling overwhelmed, often sensory or emotional. Unlike a tantrum, a meltdown isn't goal-driven and isn't something a child can simply choose to stop.
Executive function
The brain's management system: planning, starting tasks, organizing, remembering steps, and shifting between activities.
