A simple self-assessment checklist — a handful of yes/no questions tied to the specific assignment's requirements — catches a surprising number of avoidable mistakes before a teacher ever sees the work: a missing citation, an unanswered part of a question, a forgotten file attachment.

Beyond catching errors, the habit of pausing to check work against explicit criteria builds a self-editing skill that transfers well beyond any one assignment. Students who consistently self-check tend to produce noticeably fewer careless mistakes over a semester, independent of how much they know.

The checklist works best when it is short — five items or fewer — and specific to the task, rather than a generic list that starts to feel like a formality students skip.
