In 1987 the Ohio State Board of Education adopted new requirements for teacher education and teacher certification. This included the implementation of competency testing in Ohio, using the National Teacher Examination (NTE) as the certification examination. Correlation and regression analyses were performed on data collected between 1982 and 1989 on Ohio State University (OSU) teacher education graduates. Grade point average (GPA) and American College Testing (ACT) composite scores, and NTE results were correlated. In general, the high correlations were among the NTE measures and between these measures and the ACT scores. Regression analyses of the data indicated that ACT proved to be a better predictor of the NTE scores than GPA. The data suggest that efforts to improve the quality of OSU teacher education students should focus on students with higher ACT scores. Many educators advocate the development of a more comprehensive student assessment program that more accurately reflects the complexity and richness of teaching. Appendixes include seven tables displaying the data. (IAH)
