Grading Students. - Practical Assessment, Research & Evaluation

Some instructors record letter grades for tests and assignments, and others record numerical values, often the percent correct on tests. Later, under either method, the grades are averaged, often employing a weighting process designed to make some grades count more heavily than others. Discussion of the merits of different approaches usually centers around the question of whether it is better to average letter or numerical grades or around some feature of the weighting process.
