The Test of Visual Perceptual Skills (non-motor) Upper Level is Not a Valid Predictor for the Outcome of Driver Education

In order to reduce the monetary and personal costs of driver training for persons with cerebral palsy, it is of interest to find a predictor that is able to select potential license holders. Previous research has shown that such a predictor could be one that assesses visual perception. In the present study, the Test of Visual Perceptual Skills (non-motor) Upper Level, was validated for predicting the outcome of driver education. It was found that using the test for this purpose could not be recommended. The findings of the present study were not in accordance with the results of other studies on the predictive value of perceptual tests regarding the ability to drive, owing to the use of different methods. Future studies should focus on cross-validation of perceptual tests for different types of independent variables, such as driving license or not, accident involvement and driving ability.
