Test scores are important to students because these scores are often the major determinant of course grades. There is an implied and generally accepted contract between teachers and students that the tests will be representative of materials reflecting the purposes of the course and that the tests will be developed, administered, and graded fairly. In those cases in which there is an actual or perceived material departure from this implied contract, students may take issue with it (Poppen and Thompson). Since this contract itself is often implied, the procedures to deal with perceived breaches are not well understood; hence, students may react to perceived breaches in an aggressive, even hostile manner.
