The Assessment of Basic Learning Abilities (ABLA) is a tool that is used to assess the learning ability of individuals with intellectual disability (ID) and children with autism. The ABLA was recently revised and is now referred to as the ABLA-Revised (ABLA-R). A self-instructional manual was prepared to teach individuals how to administer the ABLA-R (DeWiele, Martin, Martin, Yu, & Thomson, 2011). Using a modified multiple-baseline design across a pair of university students, and replicated across four pairs, we evaluated the effectiveness of the ABLA-R self-instructional manual for teaching the students how to administer the ABLA-R. Each student: (a) after examining a brief description of the ABLA-R, attempted to administer the ABLA-R to a confederate role-playing an individual with ID (Baseline); (b) studied the ABLA-R self-instructional manual (Training); and (c) re-attempted to administer the ABLA-R to a confederate (Post-Training Assessment). Participants who achieved at least 90% accuracy in conducting the ABLA-R in their Post-Training Assessment then administered the ABLA-R to an individual with ID in a Generalization Assessment. Although additional research is needed, our results suggest that the self-instructional manual is an effective tool for training individuals to accurately administer the ABLA-R.
