QUESTION: I would like to know if a teacher or parent is allowed to make edits and recommendations on a student's writings?
ANSWER: Having an outside proofreader is a longstanding tradition for writers of all stripes. Students may certainly let an adult read over their submission before sending it. We would suggest that the adult may then offer editing and revision suggestions, but should explain the reasons for those suggestions as a teaching opportunity. Then the student should be allowed to make those changes themselves. This way they pick up grammar tips for the future, in addition to having a cleaner story or poem.
It goes without saying, however, that in no way should a parent do any of the writing themselves.
