Abstract: Given the importance of competencies in functional behavior assessment (FBA) and behavioral interventions among teachers for managing problem behaviors among children with autism spectrum disorder (ASD) and other developmental disabilities, a previously reported ability in behavior assessment and interventions for teachers (ABAIT) needed improvements in the multiple-choices by adding a 'don't know' option. This study reports on the psychometric properties of this revised scale (ABAIT-R) among 102 special educators assessed using Rasch models. It was found that the model had good fit and a wide spread of difficulties (3.63 to - 2.60). ABAIT-R had good targeting (over 85%) and high reliability (0.79). The assumptions of the model were met recommending sufficiency for the use of summated score from ABAIT-R among teachers.
