In order to evaluate the degree of neurological knowledge in a general practitioner (GP), and given the lack of a useful instrument with which to do so, we propose the drawing up of a neurological knowledge test which would give adequate psychometric guarantees. By using a broad-based sample of professionals working in Neurology (GPs, non-specialised paediatricians, and neurologists), along with sixth year medical students, and the combined work of a family doctor, a psychometry expert, a professor of neurology and two clinical neurologists, we managed to develop a multiple choice test (MCT) with 36 items that were both objective, valid, and reliable. This could be a useful means of evaluating the neurological knowledge of a GP.
