The paper argues that grammar correction in L2 writing classes should be abandoned, for the following reasons: (a) Substantial research shows it to be ineffective and none shows it to be helpful in any interesting sense; (b) for both theoretical and practical reasons, one can expect it to be ineffective; and (c) it has harmful effects. I also consider and reject a number of arguments previously offered in favor of grammar correction.
