As the need to train more teachers to work in inclusive classrooms increases, college instructors should identify and implement course assessments measuring their effectiveness in training practices. Skills in managing the challenging behaviors of students with disabilities, such as autism and emotional disturbances are important for teachers worldwide. The purpose of this paper is to explore the use of a course assessment to develop Functional Behavior Assessment (FBA) and Behavior Intervention Plan (BIP). The course assessment used in this study was developed, revised, and then implemented to evaluate participants' knowledge to identify, assess and develop plans to improve challenging behaviors of students with behavior disabilities. The course assessment was used in training teachers who currently hold general education certification in obtaining special education training. All participants were new teachers, previously certified in childhood education, and seeking additional certification in special education. Results show there were significant differences across the years of implementation of the study. The paper includes recommendations for other institutions of higher education to utilize similar course assessments into their teacher training programs. (Contains 3 tables.)
