What percentage of students with intellectual disabilities spend their time in a separate setting?

Special education encompasses the programs which serve students with mental, physical, emotional, and behavioral disabilities. The major law governing special education is the federal Individuals with Disabilities Education Act, which guarantees a “free appropriate public education” to children with disabilities and mandates that, to the “maximum extent appropriate,” they be educated with their nondisabled peers in the “least restrictive environment.” Read more.

Are schools overidentifying minority students with disabilities?

Federal law requires that states monitor their districts for overidentifying students with disabilities. Several studies have found that minority students are actually being underidentified for disabilities.

But some new studies are uncovering more nuanced findings, suggesting that minority students are overidentified in some contexts, and underidentified in others. Read more.

What are the demographics of special education teachers?

Although research has shown that students often do better in school when they have a teacher of the same race, just over 83.5 percent of special education high school teachers in public schools are white, higher than the teaching population as a whole, according to the most recent data available. But only about half of all students receiving special education services are white, according to 2017-18 data.

Inclusion statistics

A majority of special education students—66 percent of those ages 6-21 and 5-year-olds in kindergarten—spend 80 percent or more of their time in regular education classes, according to 2020 data. That number has more than doubled in recent decades. In 1989, only 31.7 percent of students ages 6-21 spent 80 percent or more of their time in regular classes.

Getting students with disabilities into general education classrooms is not a silver bullet, researchers say. Read more to learn what else needs to happen to raise academic outcomes for students with disabilities.

Learning disabilities statistics

The specific learning disabilities category is the most common one covered under the Individuals with Disabilities Education Act—in 2020-21, 32.7 percent of students with disabilities had specific learning disabilities.

Autism statistics

Eleven and a half percent of all students with disabilities have been diagnosed with autism alone, according to 2020-21 data.

Which disability categories have grown the most?

In the past decade, the number of students with disabilities as a percentage of total enrollment has increased a small amount, from 13 percent in 2010-11 to 14.5 percent in 2020-21.The mix of disabilities those students have, however, has changed dramatically.

The percent of students with disabilities who had a specific learning disability, like dyslexia, decreased from 36.7 percent in 2010-11 to 32.7 percent in 2020-21. And the percent of students with disabilities with autism almost doubled, from 6.5 percent to 11.5 percent.

How much money is spent on special education by the federal government?

In fiscal year 2018, the federal government earmarked $12.3 billion for the education of children ages 3-12 with disabilities. That’s only about 15 percent of the excess cost of educating students with disabilities, compared with the cost of educating a general education student. The federal government under the 1975 Individuals with Disabilities Education Act set a goal to pay states up to 40 percent of the excess cost. It never reached that goal.

What is the student-teacher ratio for special education students?

In 2016, there were 17.1 special education students for each special education teacher in the United States. That’s higher than the overall student-teacher ratio of 16.2 students per teacher.

From 2006 to 2016, the number of special education teachers has decreased by 17 percent, while the number of special education students only dropped by 1 percent. Read more about how that plays out on the school level.
