The authors report on two studies showing that the Slosson Intelligence Test yields higher scores than the Peabody Picture Vocabulary Test for both nursery school and third-grade children, indicating that care should be taken when the SIT is used for intellectual screening. (Author)

Study investigated relative merits of using teacher judgment and Slosson Full-Range Intelligence Test (SFRIT) to estimate students' math and reading achievement. Analyses of students enrolled in a remedial-reading program, showed that the SFRIT recovered more variance from the distributions of math and reading tests than did teacher judgment. (RJM)

The Slosson Intelligence Test, unlike most current measures of intelligence, uses a ratio method of mental age divided by chronological age to obtain an IQ score. Standard deviations are not stable across age levels. It is concluded that the Slosson is inappropriate for use in the diagnosis of mental retardation. (Author)

Examines the concurrent validity of the Slosson Full-Range Intelligence Test (S-FRIT) by comparing S-FRIT scores to the scores of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and the Woodcock-Johnson Tests of Achievement-Revised (WJ-R). Results revealed that the S-FRIT scores were more related to overall intelligence,…

For 72 elementary school students, Slosson Intelligence Tests (SITs) administered by school counselors correlated significantly with school psychologist-administered Wechsler Intelligence Scale for Children-Revised (WISC-R) (r=.75). Slosson intelligence quotient (IQ) correlated significantly higher with WISC-R Verbal IQ than with Performance IQ.…

Compared the SIT with the WISC-R for a group of intellectually gifted students. Results indicated reduced correlations between the measures. (Author)

This study suggests that the Peabody Picture Vocabulary Test and the Slosson Intelligence Test measure different and limited aspects of a child's ability and are only rough estimates of his/her capability of what is generally termed intelligence. Scores from either should be interpreted with care and in light of other information about a child.…

The S.I.T. is an age scale of intelligence with demonstrated reliability and high validity coefficients correlated to the Stanford-Binet. The items of the SIT were classified according to a scheme resembling Valett's classification of Stanford-Binet test items. A comparison of the classifications is made. (Author)

This study investigated the efficacy of predicting academic achievement as measured by the Wide Range Achievement Test, using the Slosson Intelligence Test For Children and Adults as the predictor. Results indicate that the Slosson IQ significantly predicts Wide Range standard scores. (Author)

The mean IQ on the Slosson Intelligence Test (SIT) was substantially higher than expected based on the earlier Peabody Picture Vocabulary Test (PPVT) scores. Sampling error and examiner error were excluded as explanations. Results suggest that the PPVT and SIT yield different scores and lack comparability. (Author)

The Slosson Intelligence Test (revised norms) (SIT) and the WISC-R (Wechsler Intelligence Scale for Children-Revised) were compared. Results provide a moderate degree of support for the concurrent validity of the revised SIT norms, using the WISC-R as the criterion. However, the intelligence quotients on the two tests may not be interchangeable.…

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)

An item analysis profile sheet to accompany the Slosson Intelligence Test (SIT) is helpful in providing a functional test interpretation. The lack of recorded technical and statistical information is a serious concern. Without such information, a practitioner could not use the Item Analysis of SIT with confidence. (Author)

Low income and middle income four- and five-year old children were shown stimuli in three forms: objects, colored pictures, and black and white line drawings taken from commonly used assessment instruments, and were asked to label the stimuli. Results indicated both groups of children labeled the objects more successfully than the pictures.…

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)
