Although it is important to evaluate the intended outcomes of high-stakes testing, it is also important to evaluate the unintended outcomes, which might be as important or more important than the intended outcomes. The purpose of this paper is to examine some of the unintended outcomes of high-stakes testing, including those related to: (a) using tests as a means to hold educators accountable, (b) the effects on instruction, (c) the effects on student and teacher motivation, and (d) the effects on students who are at-risk of school failure. In examining the evidence, I conclude that while some unintended outcomes of high-stakes testing have been positive, many of the unintended outcomes have been negative. Hopefully, through a greater awareness of the unintended outcomes, school psychologists can work to minimize the negative effects of testing on students and educators.
