Caseload (student-to-staff ratio) is a metric commonly used by upper level administrators to inform budgetary allocations. Using a national, random sample we found that the average caseload is 133.0 students per disability practitioner. Institutions with one disability practitioner had a caseload of 154.9 students; institutions with two or three practitioners carried a caseload of 140.7 students. Practitioners working in offices with four or five full-time staff averaged 126.6 students and those with six or more full-time professionals carried a caseload of 135.2 students. Relying solely on caseload metrics to inform budgetary decisions is problematic because practitioners often have extensive workload responsibilities beyond student caseload, current caseloads may reflect overwork rather than socially-just staffing, and caseload metrics assume students use similar accommodations and these accommodations take comparable amounts of time to administer. Thus, we describe eight additional data-driven tools and illustrate how disability leaders can employ these tools for budgetary advocacy.
