Chandler and Dahlquist (2010) make the important point that the analysis of records, interviews, and observational data "does not actually verify the function of behavior" (pp. 100-101). Verification can only occur through experimental manipulation of relevant environmental variables. This process is also known as functional analysis. Some have questioned the utility of functional analyses in schools; however, Mueller, Nkosi, and Hine (2011) examined demographic and clinical data for functional analyses conducted in public school settings and described functional analysis as a viable method in such settings. Answer the question below?
Describe the behavior analytic consultation to schools (BACS) model from the point of gathering preliminary information and moving to a hypothesis testing process.
