IEP Glossary for Parents: Plain Language Guide

Special education is full of acronyms and legal language. This quick-reference glossary covers the terms you'll encounter most often in IEP meetings and documents.

The most important terms to know

You don't need to memorize everything. Start with these — they'll come up in almost every IEP meeting.

The big three

IEP, FAPE, and LRE are the foundation of special education law. If you understand what these mean and why they matter, you can follow almost any IEP conversation.

LRELeast Restrictive Environment

The requirement that students with disabilities be educated with non-disabled peers to the maximum extent appropriate.

PLAAFPPresent Levels of Academic Achievement and Functional Performance

Terms you might hear about dispute resolution

  • State Complaint — a free written complaint to the California Department of Education alleging a violation of IDEA. Investigated within 60 days.
  • Mediation — a voluntary, free, confidential process with a neutral mediator from the CDE. Binding if you reach an agreement.
  • Due Process — a formal legal hearing before an administrative law judge at the California Office of Administrative Hearings (OAH). The most powerful — and most adversarial — option.
  • Manifestation Determination — a required meeting when a student with an IEP faces a suspension of 10+ days, to determine whether the behavior is related to the disability.

Tips for navigating IEP language in meetings

  • Always ask for clarification when you hear a term you don't recognize. You are entitled to a plain-language explanation.
  • Watch out for vague language in IEP documents: "will improve," "will work on," "will demonstrate growth" are not measurable goals.
  • When the team uses a phrase that sounds like a limitation ("that's not available," "we don't do that here"), it's worth asking for the legal basis.
  • Keep a copy of this glossary in your folder — you can reference it during the meeting.
