One assessment. Two kinds of judgement.
The MSRA is designed to assess how candidates apply knowledge and professional judgement—not simply how many facts they can recall. The exact role of the score varies by specialty and recruitment round, so candidates should always check the current guidance for the programme to which they are applying.
Current official guidance describes a 170-minute assessment: 95 minutes for Professional Dilemmas and 75 minutes for Clinical Problem Solving.
