This article describes an evaluation method for spelling and grammar checkers and gives the results of its application to two French checkers. The evaluation process follows closely the ISO/IEC and EAGLES guidelines, and defines precisely the evaluation metrics, so that they can be easily reproduced. The choice of professional translators as user profile entails the use of a corpus of spelling mistakes, which was collected and annotated. The metrics are divided into three sets: classification of perfect vs. imperfect sentences; detection of mistakes; correction of mistakes. The results show in which respect the two systems are the most adapted to the user needs, and the points on which they could be improved.
