TY - RPRT TI - Leveraging IEPs to Understand Special Education Services at Scale AU - Cleveland, Christopher AU - Kaler, Lindsey AU - Markham, Jessica PY - 2025 T3 - EdWorkingPaper M1 - 25-1249 PB - Annenberg Institute at Brown University DO - 10.26300/t22y-r243 UR - https://edworkingpapers.com/ai25-1249 AB - 7.5 million (15%) U.S. public school students have Individualized Education Programs (IEPs) that guide $14 billion in special education services. However, the content of IEPs remains unexplored, primarily because they have been historically inaccessible to researchers at scale. In this study, we develop a coding taxonomy to categorize IEP services from digital IEP records for an entire state. We identify the diverse IEP services provided to students with disabilities. We codify 459,703 IEP services for 158,460 students into 25 categories, six subjects, four support types, five settings, five service modalities, six group types, and five personnel types. This information helps understand variation in IEP services across schools. It can inform educator training and future research on the efficacy of services. ER -
