Role of formative assessment in predicting academic success among GP registrars: a retrospective longitudinal study

The James Cook University General Practice Training (JCU GPT) programme's internal formative exams were compared with the Royal Australian College of General Practitioners (RACGP) pre-entry exams to determine ability to predict final performance in the RACGP fellowship exams.

A retrospective longitudinal study.

General Practice (GP) trainees enrolled between 2016 and 2019 at a Registered Training Organisation in regional Queensland, Australia.

376 GP trainees enrolled in the training programme.

The pre-entry exams were Multiple-Mini Interviews (MMI), Situational Judgement Test (SJT) and Candidate Assessment and Applied Knowledge Test. The internal formative exams comprised multiple choice questions (MCQ1 and MCQ2), short answer questions, clinical skills and clinical reasoning.

The college exams were Applied Knowledge Test (AKT), Key Feature Problems (KFP) and Objective Structured Clinical Examination (OSCE).

Correlations (r), coefficients of determination (R²) and OR were used as parameters for estimating strength of relationship and precision of predictive accuracy. SJT and MMI were moderately (r=0.13 to 0.31) and MCQ1 and MCQ2 highly (r=0.37 to 0.53) correlated with all college exams (p<0.05 to p<0.01), with R² ranging from 0.070 to 0.376. MCQ1 was predictive of failure in all college exams (AKT: OR=2.32, KFP: OR=3.99; OSCE: OR=3.46); while MCQ2 predicted failure in AKT (OR=2.83) and KFP (OR=3.15).

We conclude that the internal MCQ formative exams predict performance in the RACGP fellowship exams. We propose that our formative assessment tools could be used as academic markers for early identification of potentially struggling trainees.
