Associations Between DAT, CBSE, and USMLE Step 1 Exams Among Oral and Maxillofacial Surgery Residents

Area of Science:

• Medical Education
• Dental Education
• Biomedical Sciences

Background:

• The Dental Admission Test (DAT), Comprehensive Basic Science Examination (CBSE), and United States Medical Licensing Examination (USMLE) Step 1 are critical assessments in dental and medical training.
• Understanding the relationships between these foundational exams is crucial for evaluating student preparedness and curriculum effectiveness.

Purpose of the Study:

• To investigate the associations between scores on the DAT (composite and subsections), CBSE, and USMLE Step 1 performance.
• To determine if DAT performance predicts success on subsequent medical licensing examinations.

Main Methods:

• A cross-sectional study utilized self-reported survey data from oral and maxillofacial surgery residents.
• Correlation analyses were performed on DAT, CBSE, and USMLE Step 1 scores, with standardized CBSE scores used.
• Twenty-seven responses from MD-granting programs met the inclusion criteria for analysis.

Main Results:

• Significant positive correlations were observed between DAT composite and subsection scores (Academic Average, Total Science, General Chemistry, Biology) and standardized CBSE scores (r = 0.40-0.60).
• No significant associations were found between DAT or CBSE scores and USMLE Step 1 performance (r = -0.10-0.20).

Conclusions:

• DAT scores are associated with CBSE performance, suggesting it reflects early medical science readiness.
• DAT performance does not appear to predict USMLE Step 1 outcomes, indicating a divergence in what these assessments measure.
