  The SIT-R3 provides a quick, reliable index of intellectual ability in children and adults, including those who are visually impaired or blind. Widely used in schools, clinics, and industry, the SIT-R3 has been designed to be used by a vast variety of educational administrators. Specific administrators considered in this revision include teachers, principals, guidance counselors, special education and learning disability teachers, psychologists, psychometrics, and social workers who often need to evaluate an individual’s mental ability.

​  It has been constructed so that the administration and scoring of the test occur simultaneously, thus enabling the test to be given in a brief period of time. Although the SIT-R3 can not be administered to groups, individual administration overcomes shortcomings of other group tests. The SIT-R3 does not penalize individuals who are extra careful, methodical, fearful and easily upset under pressure of speed, poorly motivated, uncooperative, misunderstanding the importance of the task at hand, or have reading handicapps. All the domains found within the SIT-R3 were strengthened.
