I don't agree. I always tell my kids their work needs a second set of eyes--mom's, dad's, brother's, whoever. Careless mistakes can easily be caught and it's expected at college level. In fact, many college offer a Free proofreading service. Some people might just feel comfortable with who they know--mom. I review my kids' work, when I have time. I've asked teachers if that's ok and they've said Yes. I don't re-write, but point out blatant errors. If I don't do this, no one will (teacher's don't seem to have time anymore to give thorough review) and stuff often comes back with a single grade at the top--no other marks or corrections or comments. I think proofreading aids them in learning, and that's what we want, right? I know a teacher who still proofreads her college daughter's work. I proofread my ex-boyfriend's thesis (even though I knew nothing about computer programming). When I was working, even though I was in charge, I always had someone read my reports before submitting.
