This document provides guidelines for writing objective test items that effectively evaluate students' knowledge and understanding. It recommends that test questions focus on important concepts, be at an appropriate difficulty level, and be written clearly. Items should not duplicate content verbatim from textbooks, rely on other items, have only one right answer, use negative wording when possible, and avoid clues to the correct response. The document also suggests reviewing items independently and including a mix of difficulty levels and topics grouped together.
