The article reports the analysis of errors made in a printed questionnaire and the possibility of using an electronic version of the same questionnaire aiming to control those errors. Sixty Education graduate students answered an electronic version, programmed in Visual Basic, and another 52 answered a printed version. In the printed questionnaire, 95 errors were made of which 28 errors may be ignored. The other errors may cause the exclusion of respondents that made them, if all items were analyzed strictly in agreement with the instructions. The errors made in the printed version may be controlled in an electronic version by means of appropriate programming. No difficulty in answering the electronic version was reported. The advantages pointed out by the respondents and the possibility of total control of answer errors, allied with the elimination of tabulation errors by means of automatic database insertion of the responses, recommend the use of electronic version questionnaire.
