Special Education Terms Every Parent Should Know

Plain-language definitions for the acronyms and phrases that fill IEP meetings and evaluation reports. Written for Pennsylvania families.

Why this guide exists

In most school meetings, everyone at the table shares a vocabulary except one person.

That is not an accident and it is not anyone being unkind. Educators use this language every day. What it means in practice is that a parent spends the meeting trying to translate while also trying to make decisions, and the two cannot happen at the same time.

This guide gives you the language before you walk in. You do not need to memorize it. You need to recognize it when you hear it, and know which terms are worth stopping the meeting to ask about.

Terms are grouped by when you are likely to encounter them rather than alphabetically.

The foundation

IDEA (Individuals with Disabilities Education Act)
The federal law that gives children with disabilities the right to a free public education designed around their needs. It is the law behind every IEP in the country.
Chapter 14
Pennsylvania's own special education regulations. They sit on top of IDEA and in several places give families more than federal law requires. When someone says "Chapter 14," they mean the Pennsylvania rules.
FAPE (Free Appropriate Public Education)
Your child's right to an education that meets their individual needs, at no cost to you. The word doing the most work here is appropriate. It does not mean the best possible program. The U.S. Supreme Court decision in Endrew F. set the standard: a program reasonably calculated to enable your child to make progress appropriate in light of their circumstances. Not trivial progress. Progress that means something for your child.
You are a member of the team
This is the most important line in this guide. Under federal law, parents are equal members of the IEP team, not guests who are informed of decisions. You have the right to participate in every meeting where identification, evaluation, placement, or FAPE is discussed, to bring someone with you, to ask for a meeting at any time, and to disagree.
LRE (Least Restrictive Environment)
The requirement that your child be educated alongside children without disabilities as much as is appropriate for them. Removal from the regular classroom has to be justified, not assumed.
Gaskin
A Pennsylvania class action settled in 2005 that changed how LRE works here. Because of Gaskin, your child's IEP team must consider whether the goals can be met in the regular classroom with supplementary aids and services before considering a more restrictive placement. If a team proposes moving your child out of the regular classroom, this is the question to ask first.
Section 504
A federal civil rights law that protects students with disabilities from discrimination. Broader than IDEA in who it covers, narrower in what it provides.
Service Agreement
In Pennsylvania, this is the document that spells out a student's Section 504 accommodations. Other states call it a 504 Plan. Same idea, different name. It comes from Chapter 15 of the Pennsylvania Code.
ADA (Americans with Disabilities Act)
Civil rights law covering disability in schools, workplaces, and public spaces. Occasionally relevant to school facilities and programs.

Getting evaluated

Child Find
The school district's legal obligation to identify and evaluate children who may have a disability. This duty belongs to the district whether or not a parent asks.
PTE (Permission to Evaluate)
The form a district gives you asking for consent to evaluate your child. Nothing can happen without your signature. You can request an evaluation yourself at any time, and your request should be in writing.
ER (Evaluation Report)
The document produced when the evaluation is finished. It contains testing results, observations, teacher and parent input, and the team's conclusion about whether your child qualifies for special education.
RR (Reevaluation Report)
The same thing, done again later. Reevaluations happen at least every three years. For students with an intellectual disability, Pennsylvania requires it every two years, and that one cannot be waived.
PTRE (Permission to Reevaluate)
Your consent for the district to evaluate your child again.
Consent, and taking it back
The district cannot evaluate your child or begin special education services without your written consent. You can also revoke consent later, in writing. Revoking consent is a significant step with real consequences, so understand them before you do it.
IEE (Independent Educational Evaluation)
An evaluation done by a qualified professional who does not work for the district. If you disagree with the district's evaluation, you may request an IEE at public expense. The district must then either pay for it or file for due process to defend its own evaluation. It cannot simply tell you no and leave it there.
Eligibility
Qualifying for special education requires two things: a disability in one of the categories the law recognizes, and a need for specially designed instruction because of it. A diagnosis alone does not automatically qualify a child.
Twice Exceptional (2e)
A student who is both gifted and has a disability. These students are frequently missed, because strengths and struggles mask each other and the child appears average.

Timelines you can hold a district to

These are Pennsylvania deadlines, not suggestions. Most parents never learn them, which is exactly why they slip.

10 calendar days to give you the form
Once you ask for an evaluation, the district must give you the Permission to Evaluate form within 10 calendar days. That clock runs even if the district is closed for a holiday.
60 calendar days to finish the evaluation
After you sign and return consent, the district has 60 calendar days to complete the evaluation and give you the report. Summer break does not count toward those 60 days.
10 school days to read it before you meet
You must receive a copy of the evaluation report at least 10 school days before the IEP meeting. This exists so you can read it, think, and arrive with questions rather than seeing it for the first time across the table.
30 calendar days to hold the IEP meeting
Once the evaluation report is complete, the IEP meeting must happen within 30 calendar days.
10 school days to put the IEP into practice
After the IEP is finished, it must be implemented no later than 10 school days later. A signed document that nobody is following is not an implemented IEP.
If a deadline passes
Put it in writing. A short, dated email asking where things stand creates a record, and the record is what matters later.

The documents

IEP (Individualized Education Program)
The legal document describing your child's needs, the goals for the year, and everything the school will provide. Not a suggestion. A binding commitment.
GIEP (Gifted Individualized Education Program)
Pennsylvania's separate plan for gifted students. Governed by its own regulations, Chapter 16.
Single Plan
For a student who qualifies for both special education and gifted support, Pennsylvania allows one combined plan rather than two separate documents. If your child is twice exceptional, this is worth asking about.
NOREP (Notice of Recommended Educational Placement)
Pennsylvania's form telling you what the district proposes to do and giving you the chance to approve or refuse. Read this one carefully. It also records what the team considered and rejected, which is often the most informative part of the document.
Prior Written Notice
Formal written notice a district must give before proposing or refusing a change in your child's identification, evaluation, or placement. The NOREP serves this purpose in Pennsylvania.
Procedural Safeguards
The booklet listing your rights as a parent. Districts must give it to you at least once a year, and also when you first request an evaluation, when you file a complaint or due process request, when a disciplinary removal changes your child's placement, and any time you ask for it. Most parents never open it. It is worth thirty minutes of your time.

Inside the IEP

Present Levels (PLAAFP)
Short for Present Levels of Academic Achievement and Functional Performance. The section describing where your child is right now. Every goal in the document should trace back to something described here.
Baseline
The starting measurement for a goal. Without it, there is no way to say whether progress happened. If a goal lists a baseline as "to be determined," ask when it will be taken and with what tool.
Measurable Annual Goal
What your child is expected to achieve in a year. A real goal names the skill, the conditions, and the number that counts as success. "Will improve reading" is not a measurable goal.
SDI (Specially Designed Instruction)
Changes to how material is taught, made specifically for your child. This is the heart of special education and the part most often left vague.
Accommodation
A change in how your child accesses learning, without changing what they are expected to learn. Extended time, preferential seating, text read aloud.
Modification
A change to what your child is expected to learn. Fewer problems, simplified material, different standards. Modifications can affect diploma track, so ask about long-term implications before agreeing to them.
Supplementary Aids and Services
Supports that allow your child to be educated with children who do not have disabilities. Because of Gaskin, the team must consider the full range of these before proposing a more restrictive placement.
Related Services
Services your child needs in order to benefit from special education. Speech, occupational therapy, physical therapy, counseling, transportation.
Supports for School Personnel
The section describing what training and support the adults working with your child will receive. It is frequently left blank. If your child has a behavior plan or specialized communication supports, this section matters enormously.
Service Minutes
How much of each service your child receives and how often. Minutes alone tell you very little. Ask who delivers it, in what setting, in what size group, and what instruction is missed during that time.
ESY (Extended School Year)
Services during summer or other breaks for students who need them in order to receive FAPE. The team must weigh seven factors, and no single factor decides it. Regression over breaks is one factor, not the only one. For students with severe disabilities, the group the law calls the Armstrong target group, Pennsylvania sets hard deadlines: the IEP review meeting must happen no later than February 28, and the NOREP must be issued no later than March 31. Those dates exist so a family has time to challenge a denial before summer arrives. Being found eligible should always be followed by a written description of what will actually be provided.
Transition Services
Planning for life after high school, covering further education, employment, and independent living. Pennsylvania requires this earlier than federal law. Transition must be addressed in the first IEP that will be in effect when your child turns 14. Waiting until after the fourteenth birthday is not acceptable.
Progress Monitoring
How the school tracks movement toward goals. You are entitled to progress reports on a regular schedule, generally as often as report cards go out.

Behavior and discipline

FBA (Functional Behavior Assessment)
A study of why a behavior is happening. What comes before it, what follows it, and what purpose it serves for the child. Good behavior planning starts here.
PBSP (Positive Behavior Support Plan)
Pennsylvania's term for the plan built from the FBA. Elsewhere it is called a BIP, or Behavior Intervention Plan. It describes what adults will do to teach and support different behavior.
Ten-Day Rule
Removals accumulate. Once they total ten school days in a school year, two things follow: the district must keep providing services so your child continues to receive FAPE, and a pattern of further removals can amount to a change in placement. Keep your own count, including partial days and informal calls asking you to pick your child up early.
Manifestation Determination
A required meeting, held within 10 school days of a decision to change your child's placement because of a code of conduct violation. The team answers two questions: was the behavior caused by, or substantially related to, the disability, and was it caused by the school's failure to implement the IEP. If the answer to either is yes, the removal generally cannot stand, and the team must address the behavior rather than only punish it.
IAES (Interim Alternative Educational Setting)
In three specific situations, involving weapons, illegal drugs, or serious bodily injury, a school may move a student to a different setting for up to 45 school days regardless of the manifestation determination. Services must continue there.
Stay Put
Your child's right to remain in their current placement while a dispute is being resolved. A powerful protection and one many parents never hear about.
Restraint
Physical restraint in Pennsylvania schools is restricted, must be documented, and requires that the parent be notified and an IEP meeting be offered. If you are told your child was restrained, ask for the documentation in writing.

Before special education

MTSS (Multi-Tiered System of Supports)
A framework of increasing levels of support for all students. Tier 1 is the regular classroom, Tier 2 adds targeted help, Tier 3 is intensive.
RTII (Response to Instruction and Intervention)
Pennsylvania's version of this approach. Worth knowing one thing: a school cannot use intervention tiers to delay an evaluation you have requested in writing.
SAP (Student Assistance Program)
A school-based team that connects students with help for barriers to learning, often behavioral health related. Not special education, but frequently a doorway into it.

Who is in the room

LEA Representative
The Local Education Agency representative. The district person at the table with authority to commit resources. Every IEP meeting requires one.
Case Manager
The special education teacher who coordinates your child's program and is usually your main contact.
IU (Intermediate Unit)
Pennsylvania's regional education agencies. They provide services many districts do not run themselves. Chester County is served by the Chester County Intermediate Unit, the CCIU.
School Psychologist
Typically the person who conducts cognitive and academic testing and writes much of the evaluation report.
BCBA (Board Certified Behavior Analyst)
A specialist in behavior assessment and intervention. Often involved when an FBA or behavior plan is in place.
SLP, OT, PT
Speech-Language Pathologist, Occupational Therapist, Physical Therapist. The most common related service providers.
Educational Advocate
Someone who helps you understand the process, prepare for meetings, and organize your concerns. An advocate is not an attorney and does not provide legal advice or represent you in legal proceedings. Many families work with an advocate first and bring in an attorney only if a dispute becomes formal.

When you disagree

IEP Facilitation
A neutral facilitator runs the meeting. The least adversarial option and free in Pennsylvania.
Mediation
A trained neutral mediator helps you and the district reach agreement. Voluntary, confidential, and free.
Due Process Hearing
A formal legal proceeding before a hearing officer. Pennsylvania generally limits claims to the preceding two years, so delay has real consequences.
State Complaint
A written complaint to the Pennsylvania Department of Education alleging that a district violated special education law. Different from due process, and sometimes the better tool.
Compensatory Education
The remedy when a district fails to provide what it was required to provide. If services listed in the IEP were not delivered, or FAPE was denied over a period of time, a family may be owed compensatory services to make up for it. Most parents never hear this term, and it is the one that gives a failure consequences.
ODR (Office for Dispute Resolution)
The Pennsylvania agency that administers facilitation, mediation, and due process.
PaTTAN
The Pennsylvania Training and Technical Assistance Network. Publishes guidance and training materials, much of it written for families and all of it free.

The habit worth building

Whatever happens in a meeting, ask for it in writing.

Not because anyone is acting in bad faith. Because memories differ, people move on to other buildings, and the written record is what carries into the next conversation. An email after a meeting summarizing what you understood was decided is enough, and it takes five minutes.
