In this essay the author argues that test security in student testing is a practice of questionable morality and efficacy, despite the long-standing use of the practice by test-makers. Arguing that the practice is an unthinking immoral habit, with its roots in premodern medieval views of the teacher-student relationship, the author proposes that new policies and practices be formulated to protect the inherently vulnerable student in the same way that laws now protect adult test-takers and experimentees. The author argues that secrecy priorto, during, and after a test be scrutinized carefully and minimized through the use of explicit principles-an assessment Bill of Rights-that put the students' rights on a par with those of the test-maker and that honor the modem rights of informed consent and due process.
