Learners use test questions to practice meeting the objective before an actual examination. In fact, learners should have the opportunity to practice every objective as part of the instruction. This helps reinforce their understanding of the content and determine areas requiring further study.
Test questions, when combined on a test, measure the learner's understanding and determine if he or she is ready to move on. Test results are sometimes used to prove an employee's achievement, or lack of achievement for purposes of settling human resource disputes.
Based on test results, we can determine how well a given unit of instruction is working and diagnose weakness in course material. If a significant number of learners consistently fail a given test question, it may indicate that the instruction for the corresponding objective is missing or unclear.
