In the 2010–11 school year, ISM conducted a one-year partial replication—using a stronger research design and a more exacting statistic—of its original six-year International Model Schools Project, a research project that focused on student performance, satisfaction, and enthusiasm. The results of the 2010–11 project, titled the ISM Student Experience Study (SES), were published by ISM in complete form as a white paper in January 2012, and summarized in Ideas & Perspectives in Vol. 37, No. 4. The following article, featuring one of the instruments derived from the SES findings, is designed to be read in the context of either of those two documents. Readers are asked to take note of the fact that the Characteristics of Professional Excellence II, shown in this article, supersede ISM’s original Characteristics of Professional Excellence, first published in Vol. 31, No.8, and then expanded upon in Vol. 32, No. 16.
