The Slosson Full-Range Intelligence Test is a reliable, individual screen that gives a balanced measure of Verbal/ Performance/Memory cognitive assessments. It differentially screens Nonverbal from Verbal abilities even when language skills are limited. The S-FRIT gives a quicker assessment and provides more information than any other brief intelligence test on the market.
Uses of the S-FRIT:
• Brief, Reliable, Individual Screen
• Quick Estimate of Verbal and Nonverbal Intelligence
• Planning of Educational Programming
• Screening New School Entrants and Independent Schools Admission Testing
All the S-FRIT items are arranged according to levels of difficulty. The examiner simply presents items at suggested starting points by chronological age. When the examinee fails 8 items in a row, testing is completed and the examiner very quickly gets a picture of the individual’s mental abilities.
Mental Abilities Assessed:
• Verbal Skills
• Quantitative
• Recall Memory
• Abstract Performance Reasoning
The Brief Score Form has a unique color coding system, which tabulates Standard Scores in seconds. It also separates the index items and the Full-Range Intelligence Quotient. The examiner can also test for the Best Global Index using specific questions which correlate
highest with the S-FRIT total score. The Rapid Cognitive Index may be given, using half the test items, to determine Verbal, Abstract, Quantitative, or Memory subdomains in approximately 15 minutes.

Statistical and Technical Information:
Standardized on a representative sample of 1,500 individuals across 37 states, Internal Consistency Reliability for median values range from .96 to .98, mean=100, and a standard deviation=16. Standard error of measurement at age 10 is 2.77. The criterion validity studies indicate a correlation between the Full Scale WISC-R IQ and the Full Range S-FRIT IQ to be .89.
The S-FRIT is intended to supplement the use of more extensive cognitive assessment instruments, such as the WISC-III, K-ABC, and the Stanford-Binet IV, to facilitate screening in charting cognitive progress. The test can be given by regular or special education teachers, psychologists, counselors, or other personnel who have taken basic courses in statistics and/or tests and measurements.
