Public schools have hired more than 460,000 additional instructional aides and student support staff over the past two decades, even as enrollment grew by just 4 percent, according to a new analysis published by the Reason Foundation. These two job categories—which include teacher assistants, psychologists, social workers, and speech pathologists—accounted for more than half of all new public school hires between 2002 and 2023. Inflation-adjusted per-pupil funding climbed from $14,969 to $20,322 during this period, with much of the increase going toward staffing that expanded far faster than student numbers.
The data show that public school staff grew by 15.1 percent nationwide while student enrollment rose by just 4 percent. Non-teaching staff increased by 22.8 percent, compared to a 7.6 percent rise in the number of teachers. Student support staff grew by 230,793 employees, while instructional aides increased by 230,440—together representing 51.7 percent of total staffing growth. In contrast, the three categories that make up central office staff accounted for just 17.6 percent of all new hires. Between 2007 and 2023, special education staff alone increased by 255,332 employees, making up an estimated 40.4 percent of all new staff added to public school payrolls. The number of students served under special education rose from 13.4 percent to 15.2 percent of total enrollment, adding about 1.1 million students with individualized education plans. Autism diagnoses jumped more than eightfold, increasing by 866,089 students, while diagnoses for conditions including ADHD more than tripled.
The report finds that special education has played a consequential role in staffing growth, accounting for an estimated 77.8 percent of new teacher positions and 76.2 percent of new instructional aide positions between 2007 and 2023. But the analysis also points to another driver: the growing popularity of "whole-child" school models that prioritize students' mental health, medical needs, and social services alongside academics. Cornell University economist Maria D. Fitzpatrick, quoted in the report, notes that these models view schools not just as places for reading, writing, and math, but also prioritize "children's physical, mental, and emotional health, community engagement, and social environment." Nationwide, an estimated 8,000 to 10,000 community schools now operate—representing 6 to 8 percent of all public schools—with California alone allocating more than $4 billion to support thousands of such schools in mostly low-income neighborhoods.
The report warns that with enrollment projected to fall by another 2.5 million students by 2032 and budgets tightening, dollars spent on counselors, social workers, and other support staff can't be used to boost pay for effective teachers or those in shortage areas like math and science. While some studies show benefits from whole-child strategies, the research "is far from conclusive and doesn't warrant the substantial investments made in the last couple of decades," according to the analysis. The report concludes that policymakers must ensure public education's largest budget line item—staff compensation—is spent in ways that support schools' core academic mission and improve student outcomes, particularly as schools face falling enrollment and stagnant test scores.
