Book Reviews: Evaluating with Validity

In the editor's opinion, this volume is sufficiently important that EEPA readers ought to hear from more than one reviewer concerning its quality and contribution to evaluation. Three senior reviewers were selected, therefore, who might vary in their familiarity with and support of House's appoach to evaluation. Each reviewer was not informed that two others were reviewing the volume in order that he would not, even unconsciously, adopt anything like an "assigned stance" toward this work. The result is three independent reviews that indicate strong differences of opinion about House's latest volume on evaluation.
