<p dir="ltr">Early childhood special educators are tasked to implement specially designed instruction to make the general curriculum accessible to students receiving special education services (Indiana Department of Education, 2024). Educators may use preference assessments to aid in identifying student preferences in order to develop individualized supports for students, such as the identification of potential choice options (White et al., 2022) or the identification of putative reinforcers for behavioral interventions (Conine et al., 2021; Kang et al., 2013). In this study, four special education preschool educators were trained to implement the free operant (FO) preference assessment through a video-based training package, consisting of a training video and video self-monitoring. During training, teachers watched a training video, practiced implementing the procedure through roleplay with a researcher, and self-evaluated their videorecorded roleplay performance to a procedural checklist. Results indicated that basic functional relationship between the training package and educator’s FO implementation fidelity and three of the four educators met mastery for the FO with the training package alone. Implications of this study will be discussed.</p>
