Summary Thoughts There is unquestionable need for identification and use of scientifically based and effective practice methods with students with EBD. Initial steps have been taken to advance and orchestrate the field's use of effective methods. We particularly praise the work of the Peacock Hill Working Group (1991) and Lewis and his colleagues (2004). These initial efforts to promote use of methods that have proven utility and to bring attention to the need for universal stan- dards for programs for learners with EBD form the founda- tion for ensuing models that further clarify how to improve student outcomes. We offer the model discussed in this arti- cle as an additional step toward outlining the essential ele- ments that underpin utilitarian programs for students with behavioral and emotional challenges. We close with themes that have resonated throughout our article. Effective and research-based practices are of oreat sionificance. hnwavar attainment of nocitive ont.-
