Abstract

The Council for Exceptional Children (CEC) recently released updated standards regarding how to determine whether any particular intervention may be deemed an evidence-based practice (EBP). As new criteria regarding the acceptance of any specific intervention as evidence-based become available, the question arises: Would the application of new standards to studies completed under the older guidelines result in changes to past conclusions? The current study examined if changes in EBP standards might change the classification of an exemplar practice that was previously designated as an EBP. In this case, we examined video modeling (VM), an accepted practice regarding skill acquisition in special education as an exemplar practice. In order to determine if the new CEC 2014 standards would impact a previously determined EBP finding, a re-examination of Bellini and Akullian's (2007) frequently cited meta-analysis that focused on VM as an intervention for individuals with autism spectrum disorders (ASD) was conducted. The results revealed that if Bellini and Akullian had conducted their review using updated CEC 2014 standards, VM applied to individuals with ASD would not have been classified as an EBP.
