Learning practices use IQ tests to help distinguish children for special education and gifted education programs and to offer additional support. Despite the hype, the importance, usefulness, and legitimacy of the IQ test are still hotly debated among educators, social scientists, and experts. Stefan C. Dombrowski, a psychologist from Rider University studies the effectiveness of IQ tests using precise statistical techniques. He believes that IQ tests do have meaning and are valid measures of intelligence when they are understood correctly. Although a few amendments are required, he agrees that IQ tests can still be useful as one part of an overall evaluation of the whole person.
