A writing center usually offers individualized conferencing whereby the writing tutor offers his or her feedback on the piece of writing at hand; a writing tutor's main function is to discuss how the piece of writing might be revised. However, the tutor usually does not proofread nor edit the student's work. Instead, the tutor facilitates the student's attempts to revise his or her own work by conversing with the student about the topic at hand, discussing principles and processes of writing, modeling rhetorical and syntactical moves for the student to apply, and assisting the student in identifying patterns of grammatical error in his or her writing.
