This document provides guidance on correcting mistakes made by students during tutoring sessions. It lists examples of mistakes that should and should not be corrected. Mistakes that should be corrected include replacing a word with one that doesn't make sense, reading in a way that changes the sentence's meaning, and grammatical errors. Mistakes that typically should not be corrected include errors that don't alter meaning and omitting words like "and" or "the." The document instructs tutors to have students finish sentences before correcting them and to point out missed words for the student to repeat.
