A precision filing test involving the reduction of a steel cylinder to a perfect cube with the use of a hand file and bench vise was devised as a diagnostic tool for the early detection of freshman students having technic difficulties. The test was administered to 188 freshman dental students in three classes at Loma Linda University, School of Dentistry. Subjective and objective scores were then statistically compared with subsequent technic and clinic grades of the students. The simple linear correlations between the predictor test variable and criterion grades were statistically significant for one class and for the combined classes but not for the other two individual classes. Furthermore, the correlations were generally less than 0.4, indicating no substantial predictive value. Multiple correlations involving the study variables showed even less statistical significance. Therefore, the test could not be considered to have a significant predictive value.
