The IEP Files™ Defines That: Why the Words Matter

Special education has its own language—and families are often expected to understand it while making high-stakes decisions about their child’s education.

That is why I created The IEP Files™ Defines That.

This series is not about memorizing special education vocabulary. It is about becoming fluent enough in the process to recognize what is missing, ask better questions, and make informed decisions before agreeing to a plan.

A term on an IEP is never just a term. It can determine what the school must consider, what it must document, what support a student receives, and what options a parent has when the process breaks down.

Every Wednesday on TikTok, I break down one special education term in plain language. At the end of each month, I will bring the four terms together here on the blog—because understanding each definition matters, but understanding how the terms work together is where families begin to build strategy.

September Recap: Four Terms Families Need to Know

1. Present Levels of Academic Achievement and Functional Performance (PLAAFP)

The PLAAFP is the foundation of the IEP. It should explain where the student is currently performing, how the disability affects the student’s involvement and progress in the general education curriculum, and what the available data show about the student’s needs.

Why it matters: measurable annual goals, services, supports, accommodations, and placement decisions should be connected to a clear and accurate description of the student’s present levels. If the foundation is vague, outdated, or incomplete, the rest of the IEP may not be built to address the student’s actual needs.

Questions to ask:

• What current data support this statement?

• What can my child do independently?

• Where is my child struggling, and how does the disability affect access and progress?

• Does this section describe needs clearly enough to guide goals and services?

2. Ableism

Ableism includes beliefs, language, policies, and practices that treat disabled people as less capable, less valuable, or less deserving of access and opportunity.

In special education, ableism may appear through lowered expectations, decisions based on disability labels instead of individualized data, exclusion disguised as support, or language that treats access as a favor rather than a right.

Why it matters: families should be able to distinguish an individualized decision supported by data from a decision shaped by assumptions about what a disabled student can or cannot do.

Questions to ask:

• Is this recommendation based on data or an assumption?

• Has the team considered the supports the student needs to participate successfully?

• Are expectations being lowered instead of barriers being addressed?

3. Educational Evaluation

An educational evaluation is the process used to collect information about a student’s strengths, needs, eligibility, and educational programming. It may include assessments, observations, interviews, record reviews, work samples, and other relevant data.

Why it matters: the evaluation should be sufficiently comprehensive to identify all of the student’s special education and related-service needs—not only the needs commonly associated with an existing diagnosis or eligibility category.

Questions to ask:

• What areas were assessed, and why were those measures selected?

• What suspected areas of disability were considered?

• Do the results explain the concerns seen at school and at home?

• What educational needs and recommendations follow from the data?

4. Prior Written Notice (PWN)

Prior Written Notice is the school district’s written explanation of a decision it proposes or refuses regarding the identification, evaluation, educational placement, or provision of a free appropriate public education to a student.

It should explain what the school proposed or refused, why it made that decision, what information it relied on, what other options were considered, why those options were rejected, and the other relevant factors behind the decision.

Why it matters: PWN creates a written record of the school’s decision-making. A meeting summary may describe the conversation; a compliant PWN should document the actual proposal or refusal and the basis for it.

Questions to ask:

• What did the school propose or refuse?

• What data did the team rely on?

• What alternatives were considered and rejected?

• Does the notice accurately reflect the parent’s request and the school’s response?

How September’s Terms Work Together

These four terms tell a larger story.

The PLAAFP identifies the student’s current needs. The educational evaluation supplies much of the data the team should use to understand those needs. Awareness of ableism helps families question whether decisions are individualized or influenced by lowered expectations. Prior Written Notice documents what the school ultimately proposes or refuses—and why.

That is the purpose of The IEP Files™ Defines That: not isolated definitions, but practical understanding families can use before, during, and after an IEP meeting.

Coming in October: Build the IEP

In October, the series moves from understanding the record to examining how an IEP should be built:

• October 7 — Accommodations: how a student accesses instruction and demonstrates learning without changing what the student is expected to learn.

• October 14 — Supplementary Aids and Services: supports that help a student learn, participate, and make progress alongside nondisabled peers to the maximum extent appropriate.

• October 21 — IEP Goals: measurable statements of what the student is expected to achieve based on identified needs.

• October 28 — Free Appropriate Public Education (FAPE): the legal entitlement that anchors the special education program and requires more than services that merely exist on paper.

The sequence is intentional: access → support → progress → entitlement.

Follow @theiepfiles on TikTok for a new definition every Wednesday. Save the videos, share them with another family, and return here at the end of each month for the full recap.

Because better advocacy starts with understanding the words being used to make decisions about your child.
