A quantitative method for the informative evaluation of teaching activities was devised using a survey from 33 experts. It is based on an evaluation, by students and two peers, of the four steps of the instructional methodology: analysis of training needs, statement of learning objectives, delivery of teaching session, and testing of student performance. Faculty evaluation is optional, and results are strictly confidential. Results of a 3-year trial of this protocol at the Alfort veterinary school are presented and discussed. Each year the method has been assessed and some changes have been implemented. It is now felt that evaluation questionnaires for lectures and tutorial sessions have been validated, while those for laboratories and clinical teaching have to be tested in a larger number of settings. At the same time, a change from informative to summative evaluation is under consideration.
