 
															50 years after IDEA promised to deliver the help students with learning and behavioral differences need, millions are still being left behind. It’s time to understand why—and how to fix it.
 
															Special education was created in 1975 to close the gap between what students need and what the regular classroom provides. But no one anticipated just how many would need help. In the half century since, the number of students found eligible for special education has exploded.
Identification rates are a function of eligibility criteria. They tell us how many students are found eligible, not how many students whose learning and behavioral differences affect their success in the classroom.
 
															Changes to eligibility criteria have pushed identification rates higher even as more students in need of support are excluded.
 
															 
															By design, special education is exclusionary: not everyone is entitled to support. But that entitlement isn’t based on objective need; it’s based on subjective determinations about the cause of students’ struggles and their untapped potential. Both of these students need the same evidence-based reading instruction, but only one of them is entitled to support.
 
															 
															 
															This subjectivity produces variability. Whether students secure support depends more on where they happen to live than whether they have an objective need.
 
															 
															Letting more students in hasn’t addressed the core problem: too many students are being left behind.
Students identified with a disability are no more likely to achieve literacy benchmarks today than they were in 1998. Nor does additional time in school–and the support of special education–seem to improve things.
In 2024, 67 percent of 8th graders tested below basic in reading on the National Assessments of Educational Progress Students compared to 72 percent of 4th graders.
These gaps are a function of today’s system: a regular classroom that was designed to provide everyone the same thing coupled with a special education system that fails to reliably make up for its shortcomings.
A different system could produce better results.
