 At present, the University of Birmingham has not fully incorporated GTA teaching into its final year OG curriculum with 150400 students placed at the BWH being taught in this way. Thus, with opinion as to the value of GTAs not yet solidified and in the absence of rigorous scientific assessment of the educational and economic benefits of GTAs, we propose a large randomised controlled trial. The RCT will compare the effectiveness and cost-effectiveness of teaching female pelvic examination to medical students using GTAs with traditional teaching using pelvic manikins.
