Level three involves examining the individual subtests strengths and weaknesses to determine fluctuation significance, and indicate this on the profile as either a strength or a weakness. Meaning of IQ Scores The IQ score provides an accurate and broadly based measure of overall intellectual functioning, g, that reports an estimate of a persons current level of areas of functioning (Kaplin, & Saccuzzo, 2005). Finally, a clear overall summary of the results and a conclusion with any recommendations in light of background information and current test data should be included (Flanagan, 2004; Groth-Marnet, 1997; Kaplin, & Saccuzzo, 2005). r The excellent reliability and well validated WAIS scales, as well as vast improvements in the structure, content, procedure, and clinical utility make extraction of more meaningful information more readily available; however, examiner precision and accuracy are required for proper administration and scoring.

Each subtest score may be tallied and compared to non-normal or brain-damaged norms to reveal deficits in brain function (Axelrod, Fichtenberg, Liethen, Czarnota, & Stuky, 2001; Crawford, Johnson, Myschalkiw, & Moore, 1997).

The validity of the test is also in question as it does not account for differences in students backgrounds and personal life so test scores do not accurately measure students abilities, but rather, it measures their ability to memorize information and test taking skills. On the WAIS, Wechsler instead compared the scores of the test-taker to those of others in their general age group. The Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Memory Scale (WMS) are 2 of the most common psychological tests used in clinical care and research in neurology. 98, .
