After a period of three years, it was decided to evaluate the impact of these courses on the worker's health of the Regionals Health Districts - RHDs, and on the professional development of the trained people. Two questionaires were sent by mail. One of them to be answered by the Directors of the 65 RHDs and the other one by professionals who attended the courses. From the 65 existing RHDs, 54 anmswers were obtained (83,1 per cent). From the 364 questionaires sent to the students, 133 were answered (36,5 per cent). The conclusions were that the majority of the RHDs introduced the Workers Health Program at regional level and the training influenced favourably activities in Worker's Health.
