Students who take the National Education Development Test (NEDT) receive predictions of their test score range for college entrance examinations including the American College Testing Program (ACT). This study was undertaken to investigate the correlation between scores on the NEDT and the ACT. Sixty female students were selected from the junior class of an urban, parochial high school with students from middle class communities. Predicted ACT scores from the NEDT were compared with ACT scores for the sample in a single group pretest-posttest design. Findings were tabulated in terms of means and standard deviations. There is a statistically significant correlation of 0.87 between scores on the NEDT and scores on the ACT. This information supports the assumption that the NEDT is a useful predictor of ACT scores. A table presents comparison findings. (Contains 10 references.) (SLD)
