Des enseignants ( N = 230) ont repondu a un questionnaire sur leurs croyances au sujet des effets du redoublement. L’analyse des donnees revele que ces enseignants attribuent de nombreux avantages au redoublement. L’analyse de la variance fait ressortir des differences significatives entre les croyances exprimees. Les repondants n’ayant pas pris connaissance des resultats de la recherche croient davantage aux bons effets du redoublement, de meme que ceux dont le diplome est un brevet plutot qu’un baccalaureat ou une maitrise. Two hundred and thirty teachers responded to a questionnaire on their beliefs about the effects of repeating a grade. An analysis of the data showed that these teachers see many advantages in repeating. Variance analysis brought out sig- nificant differences in the beliefs expressed. Respondents who were not aware of the research in this field were more likely to believe in the benefits of repeating, as did those with a teaching certificate rather than a bachelor’s or master’s degree.
