  METHODS
  the design and content validity of the questionnaire had sustained in the literature review, as well as in the opinion had been given by experts and residents. The construct validity was measure for exploratory factorial analysis, only questions with factor charge > or = 0.50 and that classified as a single factor has been retained and Cronbach's alpha coefficient was calculated.
  
  
  RESULTS
  residents (157) evaluated to 9 professors. The answer rate was of 75.1%. The questionnaire has 37 items. Five factors were identified with eigen values > or =1 which explained 52.5% of the total variance. The Cronbach's alpha coefficient was of 0.9596 for the questionnaire.
  
  
  CONCLUSIONS
  the instrument has a high grade of reliability and it can be used for evaluation and pursuit of the academic performance in medical specialities courses.
