This study examined the relationship between hours in general education and achievement in reading and mathematics for students with disabilities. The study population included more than 1,300 students between the ages of 6 and 9 years old within 180 school districts. Hierarchical linear modeling (HLM) was utilized with the Pre-Elementary Education Longitudinal Study (PEELS) data set (Institute of Education Sciences). The relationship between hours in general education and achievement in reading and mathematics was explored while accounting for student- and district-level factors. Results suggest a strong positive relationship between the number of hours students spent in general education and achievement in mathematics and reading. Implications for policy and practice in special education are presented and discussed.
