As students with severe disabilities are included in general education settings, the use of paraprofessionals has expanded to meet these students' needs. Unfortunately, paraprofessionals can have the inadvertent effect of intensifying the social isolation of students with disabilities. This study investigated the effectiveness of a training program aimed at teaching four paraprofessionals to facilitate interactions between students with severe disabilities and their peers. A multiple baseline, single-subject design across four paraprofessional/student pairs was utilized. Observational data were collected over the baseline and postintervention phases. Rates of paraprofessional facilitative behavior increased following the intervention. Additionally, rates of student interaction increased immediately and dramatically and were maintained through the maintenance probe.
