This course will provide an overview of the types of performance assessment tools used by performance management practitioners, and the historical foundations of these assessments are explored. Strategies for conducting historical assessments will be shared, including lists of documents that may be reviewed to influence interventions. Indirect assessments, including diagnostic tools and consequence analyses, will be demonstrated using both research and practical applications. Reviews of different types of direct observation strategies will also be reviewed in the context of determining interventions, and finally, the use of experimental analysis in PM practice will also be discussed, including exploring why the use of these analyses are more common in clinical ABA than performance management practice.
