Noting the lack of research comparing the Test of Nonverbal Intelligence (TONI) with other measures of intelligence, a study was conducted to ascertain concurrent validity. The TONI was compared to the Slosson Intelligence Test for Children and Adults (SIT) and the Wechsler Intelligence Scale for Children--Revised (WISC-R). Subjects, 43 males and…

The SIT Correlates highly enough with ACT scores to be considered a valid instrument for predicting acceptance and success in college. (Authors)

Substitution of the Slosson for the Benet or Wechsler with this group appears unwarranted. While SIT seems valid as brief screening instrument for class placement of primary-age mentally retarded children, it does not appear to be an adequate replacement instrument. (CJ)

A study of WISC-R and the Slosson Intelligence Test (SIT) reveal that SIT IQs were higher than WISC-R IQs in the upper range and lower in the lower range. Concludes that the SIT provides a good estimate of WISC-R full scale IQs when a regression equation is used. (Author)

Concludes that the new Slosson Intelligence Test (SIT) serves reasonably well as a quick estimate of intellectual ability but that it should not be used as an extended substitute for the more rigorous WISC-R. (FL)

This study was concerned with determining the validity of the Slosson Intelligence Test (SIT) using the Stanford-Binet Intelligence Scale (S-B), Form L-M as the validity criterion. The sample consisted of 724 students enrolled in 10 public school systems in northeastern Massachusetts. Using the Pearson-Product Moment formula a coefficient of…

Ten years of validity research concerning the Slosson Intelligence Test (SIT) is reviewed. The equivalence of the SIT to the Stanford-Binet and the Wechsler Scales is examined and the relationship of the SIT to achievement measures is described. (Author)
