THE APPLICATION OF A FACTORIAL DESIGN TO THE STUDY OF CULTURAL BIAS IN GENERAL CULTURE ITEMS ON THE NATIONAL TEACHER EXAMINATION1

This article describes a series of studies performed with the National Teacher Examinations which were designed to study the relationship between the cultural content of special sets of general culture test items and the performance of blacks and whites on these experimental items. Significant differences between the performance of blacks and whites were found in terms of black, modern, and traditional test items. A replication of the study with the same test items, and also with a different group of test items, is also described.
