Practice Guidelines have become increasingly popular at the national and international level. Practice Guidelines are a natural extension of the "evidence-based intervention" movement, and could be a mechanism to promote the use of evidence-based interventions within the field of school psychology practice and training. In this paper we review the use of Practice Guidelines in other fields and the promise and potential pitfalls associated with the development and application of Practice Guidelines within the field of school psychology. Recommendations for how to avert some of the difficulties faced by other disciplines in the development and application of Practice Guidelines are discussed. Suggestions for next steps in the profession and future research are noted. textcopyright 2005 Society for the Study of School Psychology. Published by Elsevier Ltd. All rights reserved.
