LRE? FBA? LMNOP? Anything associated with special education can sound like alphabet soup to the untrained ear, and as special educators we talk in a special lingo – re: acronyms and jargon.
Knowing special education acronyms and jargon is crucial for several reasons, especially for special education teachers, parents, and service providers.
- Misunderstandings can lead to confusion about a student’s rights, services, and progress.
- Teachers and parents who understand the terminology can better advocate for appropriate services, accommodations, and supports.
- Being familiar with the legal language helps educators follow proper procedures, avoiding compliance issues and ensuring students’ rights are upheld.
- Breaking down jargon in a way that everyone on the IEP team can understand builds trust and strengthens the team’s relationship.
- Understanding these terms helps in making informed decisions about student needs and instructional strategies.
Luckily, we’ve got a handy list of some of the most common special education acronyms (which you can also download for free here).
