Here is a brief, easily scored measure of general cognitive ability. Because it gives you a quick yet reliable estimate of verbal and nonverbal intelligence, the S-FRIT is highly useful in screening new school entrants and exceptional children, confirming other test results, determining educational placement, and charting cognitive progress. | |||||||||||||||||||||||||||||||||||||||||||||
Individually administered in just 15 to 35 minutes, the test is appropriate for ages 5 through 21 years. It contains 252 items, arranged in order of difficulty. The examiner quickly establishes a single basal and ceiling for the entire test, then scores one point for each item passed on the test’s three subscales: | |||||||||||||||||||||||||||||||||||||||||||||

The test provides a Verbal Index, Performance Index, and Memory Index, which, when added together, yield a Full-Range IQ. Also provided are several supplementary scores, including a Best g Index, which is based on S-FRIT items that correlate highly with the total score. For examiners who need a fast estimate of overall cognition, a 15-minute administration of the test, using roughly half the items, produces a quick score called the Rapid Cognitive Index. S-FRIT norms are based on a representative sample of 1,500 individuals in 37 states. | |||||||||||||||||||||||||||||||||||||||||||||
The S-FRIT gives more information than any other brief intelligence screener. It is an excellent supplement to more extensive cognitive assessments, such as the WISC-III, in charting cognitive progress. |
