This paper, based on a book on the assessment of minority students, is a critical review of the research done heretofore on intelligence testing. It deals with such issues as: the social criticism of testing through numerous lawsuits, court rulings, and in the positions taken by the Association of Black Psychologists and the American Personnel and Guidance Association; the use of IQ tests for grouping purposes; experiments related to the test environment; the self-fulfilling prophecy; and the effects of language differences on test results. It is held that the present trend points toward an expansion and elaboration of psychometrics rather than an abolition of objective tests. Among the trends are: a recognition of the need to train the users of tests to ensure that test scores are not misinterpreted and also train them in the potentialities of a variety of errors of interpretation due to technical and psychological factors which contaminate test results; a focus on measures of environment to bolster and supplement the scores from traditional tests; a call for a "pluralistic sociocultural" perspective on the testing of minorities; the development of new measures consistent with the special language characteristics of the minorities; and, an emphasis on description and prescription rather than on selection and prediction in order to facilitate equal educational opportunities.
