A new Formative Evaluation Test on Bloom's paper "Learning for Mastery" is presented. The self-instructional quiz has the principles of mastery learning in it, features instant knowledge of results coupled with prescriptive feedback, and has a non-punitive student self-scoring and item-of-difficulty identification system. It should be an effective exercise for indoctrination in the important concepts of the Bloom learning philosophy and in the implementation of formative evaluation testing. The test packet comes complete with a reprint of the Bloom article and is suitable for use as a class demonstration/experiment for education or psychology students. (LH)
