The relationship between learning disabilities and behavior disorders is well documented and has led to the development of integrated interventions that target both academic and behavior deficits in elementary school-age students. This paper describes the rationale for, development of and implementation of an integrated academic-behavior intervention called "academic and behavior combined support (ABC Support)." The intervention was developed by integrating the critical intervention elements from two single-focus interventions (i.e., repeated reading and check-in/check-out) into a single comprehensive intervention designed to improve reading fluency for early elementary school-age students with reading disorders while also strengthening their engagement and compliance with behavior expectations.
