Researchers designed and piloted a questionnaire that measures the level of implementation of exemplary middle school practices (based on the work of P. George and W. Alexander, 1993) using Rasch measurement theory. Assistant principals (n=26) participated in telephone interviews by responding to a 27-item questionnaire that contains items reflecting school scheduling practices, team teaching, teacher planning, school philosophy, tracking, and other exemplary middle school practices. Findings show that schools with block scheduling exhibited more exemplary middle school practices than did those with traditional class scheduling. In addition, 58% of the sample exhibited exemplary middle school practices based on the most distinguishing questionnaire items. An appendix contains the study questionnaire.
