The article presents a multi-faceted theory of "ideal high school student" traits. The trait system, as defined by several theories, is a translation of the teachers' belief system into educational objectives. The study focused on Bloom's taxonomies and the structural validity of its principles, using Similarity Structure Analysis. Aware of the criticism of the taxonomies, the study examines and confirms several principles underlying the taxonomies, while others are still open to reexamination. (Contains 2 figures.)
