Revised entry and selection mechanisms to medicine now include an adjunct admission test known as the HPAT. Stakeholder acceptability is a key issue. General Practitioners (GPs) represent an important stakeholder group. A questionnaire was administered to a regional sample of GPs evaluating their knowledge of the new selection system, their performance in sample HPAT questions and their perceptions of the relevance of these. 92 respondents (75.4%) reported they had little or no knowledge of the HPAT. While GPs appear to support the use of aptitude tests with 85 respondents (69.7%) adopting this position almost one third (39 respondents, 32%) either disagreed or strongly disagreed with the reforms introduced. The majority (118 respondents, 96.7%) strongly supported the use of the Leaving certificate as a selection tool (118 respondents, 96.7%). GPs performed well in the sample questions. Items from section 2 which measures interpersonal understanding were judged to be the most relevant.
