A project was undertaken to create a substantial data file containing multiple measures of learner attainment information in order to provide alternative models for teacher preparation effects through regression analysis. A general description of both the performance-based secondary-level teacher education program at Texas A & M University and the extensive data set, DENNOR, are provided. Data was gathered from a sample of 44 secondary-level student teachers and 4,656 learners taught by the student teachers. The model of instruction that the teacher education program embraces is described in detail. (Author/LH)
