The purposes of this study were to establish standardized procedures for the Nine Hole Peg Test of finger dexterity, to evaluate its reliability and validity, and to establish new clinical norms based on these standardized procedures. For the reliability and validity study, 26 female occupational therapy students were tested. Very high interrater reliability (right r = .97, left r = .99) was found. Test-retest reliability was reported to be moderate to high (right r = .69, left r = .43) and a significant practice effect was found between the test and retest occasions. Possible variables that may have affected these results are discussed. To evaluate concurrent validity, the Nine Hole Peg Test was compared to the Purdue Pegboard. The observed correlations (right r = -.61, left r = -.53) indicated that the tests are similar but not equivalent tests of finger dexterity. For the normative data study, 628 normal subjects from 20 to 94 years were tested. Data were stratified by sex and by 12 age groups to allow the therapist to easily compare patients' scores to a normative population. Data showed that females scored sightly better than males, finger dexterity decreased with age, and right-hand and left-hand dominant subjects demonstrated minimal differences in performance.
