Hi Patricia: I don't think anyone expects pretesting to be done all the time or for every class. It's a tool, and we don't use every tool on every job - nor should we do pretesting for every class. Brief pretesting can be done in three situations: * At the beginning of a class to see where your students are at. * Prior to a test to see if the students have mastered key concepts. * As a comparison between student groups, teacher groups, or clinical groups to determine to what degree similar scoring will occur. At any rate, it doesn't have to be done all the time, and it doesn't have to be comprehensive. Make that tool work for you! Regards, Barry
