Validating use of a critical thinking test for the dental admission test.

The purpose of this study was to validate the use of a test to assess dental school applicants' critical thinking abilities. The intent was to include this test on the Dental Admission Test (DAT) if it was shown to enhance the DAT's validity. Correlation and regression analyses of undergraduate and dental school performance with scores on each of the tests on the DAT battery and the California Critical Thinking Skills Test (CCTST) were performed. Data were collected from 439 third- and fourth-year dental students who consented to participate and were enrolled at one of the ten accredited dental schools included in the study. These ten dental schools were from most regions of the United States. This study concluded that including the CCTST on the DAT did not significantly enhance the DAT's validity.
