This study examined the effects of behavioral skills training (BST) on teachers' implementation fidelity of a reading racetrack (a board game designed to increase sight word fluency) with elementary students identified as struggling readers. BST, an alternative to traditional professional development, is a performance-based protocol incorporating instruction, modeling, rehearsal, and feedback. A multiple probe design across teacher-student dyads demonstrated that BST was functionally related to the teachers' implementation of a reading racetrack with 100% fidelity on at least three consecutive sessions. Additionally, students met mastery criteria for sight word acquisition and demonstrated maintenance at least one to two weeks post intervention.
