Special education is not a “small program” in today’s public schools—it is a core part of how schools serve students. The newest national data show that more students than ever are receiving special education and related services under the Individuals with Disabilities Education Act (IDEA). For school leaders, educators, and service providers, this isn’t just a statistic. It is a clear signal about capacity, staffing, compliance, and student outcomes.
At TinyEYE, we partner with schools to deliver online therapy services that support students’ IEP needs. So when national IDEA trends shift—even by a few percentage points—it changes what schools must plan for: caseloads, evaluations, service minutes, and the availability of qualified clinicians.
A Quick Refresher: What IDEA Requires
IDEA was enacted in 1975 and requires public schools to provide a free appropriate public education (FAPE) to eligible students ages 3–21. Eligibility is determined by a team of professionals who identify that a student has a disability that adversely affects educational performance and requires special education and/or related services.
IDEA also comes with reporting and compliance monitoring. Data collection to track IDEA services began in 1976, which is why we can see long-term trends and understand how student needs and service delivery have evolved.
The Big Headline: IDEA Service Numbers Reached an All-Time High
In school year 2022–23, 7.5 million students ages 3–21 received special education and/or related services under IDEA. That equals 15 percent of all public school students.
To put that in perspective:
- In 2012–13, 6.4 million students were served under IDEA.
- By 2022–23, that number rose to 7.5 million.
- As a share of public school enrollment, the percentage increased from 13 percent to 15 percent over the decade.
That change may sound modest until you translate it into real school operations. In a district with 10,000 students, moving from 13 percent to 15 percent means roughly 200 additional students who may require IEPs, evaluations, progress monitoring, and related services such as speech-language therapy or occupational therapy.
What Happened During the Pandemic—and Why the Trend Still Rose
During the coronavirus pandemic, overall public school enrollment declined. Total public school enrollment dropped 3 percent from fall 2019 to fall 2020, and enrollment in fall 2022 still had not returned to pre-pandemic levels.
Meanwhile, the number of students served under IDEA dipped slightly at first:
- From 2019–20 to 2020–21, IDEA counts decreased from 7.3 million to 7.2 million students (a 1 percent decrease).
- By 2022–23, IDEA counts climbed to 7.5 million—3 percent higher than 2019–20.
Because overall enrollment fell while IDEA counts rebounded and then grew, the percentage of students served under IDEA continued to rise each year during the pandemic, reaching 15 percent in 2022–23 (up from 14 percent in 2019–20).
For schools, this is a planning reality: even if total enrollment is down, special education responsibilities may not decrease—and may actually increase.
Disability Categories: Where the Largest Needs Are
Among students served under IDEA in 2022–23, the most common disability category was specific learning disabilities, representing 32 percent of students served.
The largest categories were:
- Specific learning disabilities: 32 percent
- Speech or language impairments: 19 percent
- Other health impairments: 15 percent
- Autism: 13 percent
From a service delivery standpoint, this distribution matters. Speech or language impairment is the second-largest category nationally—an important reminder that speech-language services are not “extra support.” They are a major component of IDEA-related services in many schools.
It also highlights why staffing shortages in speech-language pathology, occupational therapy, and mental health-related supports can quickly become compliance and access issues. When needs rise faster than hiring pipelines, schools must find flexible, high-quality ways to deliver services.
IDEA Identification Varies Widely by State
In 2022–23, across the 50 states and the District of Columbia, the percentage of public school students served under IDEA ranged from 12 percent to 21 percent.
- Highest reported percentages (21 percent): Pennsylvania, New York, and Maine
- Lowest reported percentages (12 percent): Idaho and Hawaii
Other jurisdictions also showed notable differences:
- Puerto Rico: 37 percent
- Northern Mariana Islands: 11 percent
- U.S. Virgin Islands: 9 percent
- Bureau of Indian Education schools: 15 percent
These differences can reflect many factors, including policy, evaluation practices, service availability, and demographic considerations. For school teams, the takeaway is simple: comparing your district to a national average can be useful, but comparing to your state context is often more meaningful for planning.
Race/Ethnicity Patterns: Important Context for Equity Conversations
In 2022–23, the percentage of public school students served under IDEA differed by race/ethnicity. The percentages were:
- American Indian/Alaska Native students: 19 percent
- Black students: 17 percent
- White students: 15 percent
- Hispanic students: 15 percent
- Pacific Islander students: 12 percent
- Asian students: 8 percent
For most racial/ethnic groups, specific learning disabilities and speech or language impairments were the two most common disability categories. One notable exception: among Asian students served under IDEA, autism was the most common disability category (31 percent).
For educators and administrators, these patterns reinforce the need for strong, culturally responsive evaluation practices and careful decision-making. Identification should be accurate and supportive—not driven by bias, inconsistent access, or uneven intervention opportunities.
Inclusion and Educational Environments: Most Students Are in Regular Schools
For school-age students served under IDEA in fall 2022:
- 95 percent were enrolled in regular schools
- 2 percent were enrolled in separate schools for students with disabilities
- 2 percent were parentally placed in regular private schools (and received services at public expense)
- About 1 percent were homebound/hospitalized, in residential facilities, or in correctional facilities
Just as important is how much time students spend in general education classes. Between fall 2012 and fall 2022, the percentage of school-age students served under IDEA who spent 80 percent or more of the school day in general classes increased from 61 percent to 67 percent.
This is a meaningful shift. It suggests that inclusion is increasing, and it raises the bar for how related services are delivered. When students spend more of their day in general education settings, services must be coordinated with classroom routines, teacher expectations, and real-time academic demands.
In fall 2022, more than two-thirds of students with these disabilities spent 80 percent or more of their day in general classes:
- Speech or language impairments: 89 percent
- Specific learning disabilities: 76 percent
- Other health impairments: 71 percent
- Visual impairments: 70 percent
- Developmental delays: 69 percent
This is where strong collaboration matters most: general educators, special educators, and related service providers working as one team, with goals that connect directly to classroom participation.
School Exiting Data: Graduation, Dropout, and What Schools Can Influence
For students ages 14–21 served under IDEA who exited school in 2021–22 (about 464,000 students):
- 74 percent graduated with a regular high school diploma
- 15 percent dropped out
- 10 percent received an alternative certificate
- 1 percent reached the maximum age for services
These outcomes vary by race/ethnicity and by disability category. For example, the graduation rate among exiting students was highest for Asian students (78 percent) and lowest for Black students (68 percent). By disability type, students with hearing impairments had the highest graduation rate (84 percent), while students with multiple disabilities had the lowest (40 percent).
Schools cannot control every factor that shapes these outcomes, but they can influence key drivers:
- Early identification paired with evidence-based intervention
- Consistent delivery of IEP minutes (including related services)
- Progress monitoring that leads to timely IEP adjustments
- Strong transition planning that starts early and stays student-centered
What This Means for Schools—and How Online Therapy Can Help
When IDEA service rates rise, the pressure on school systems is immediate: more evaluations, more IEP meetings, more service minutes, and more documentation. And because speech or language impairment and other high-incidence categories represent a large portion of IDEA eligibility, related services staffing becomes a central challenge.
Online therapy services can support schools by helping stabilize service delivery when staffing is tight, schedules are complex, or specialists are difficult to recruit locally. In an inclusion-focused environment—where many students spend most of their day in general education—flexible service models can help teams maintain consistency without pulling students away from core instruction more than necessary.
