Some education policy analysts have called for increased participation of young children in full-day kindergarten programs as opposed to part-day kindergarten. However, little is known about whether students with disabilities are increasingly attending these programs and what their teachers are like. This study addresses this gap by examining whether the full-day kindergarten-going patterns have changed within two nationally representative cohorts of kindergartners (Early Childhood Longitudinal Study–Kindergarten classes of 1998 and 2010). The findings suggest that a greater percentage of students with disabilities are enrolled in full-day kindergarten programs in 2010 (approximately 80%) than in 1998 (approximately 55%). Comparing full-day kindergarten enrollees between the two cohorts, there were no differences in teachers’ years of experience or degrees, though full-day kindergarten enrollees in 2010 had teachers with less early education and special education coursework. However, full-day kindergarten enrollees in 2010 were more likely to be in classrooms with a special education teacher’s aide. Implications are discussed.
