One hundred elementary‐ and middle‐school students were administered the Universal Nonverbal Intelligence Test (UNIT; B.A. Bracken & R.S. McCallum, 1998) and the Leiter International Performance Scale‐Revised (Leiter‐R; G.H. Roid & L.J. Miller, 1997). Correlations between UNIT and Leiter‐R scores were statistically significant ( p < .001), ranging from .33 to .74. The UNIT Full Scale score was 5 points higher than the Leiter‐R Full Scale score, t = 4.73, p < .001. © 2006 Wiley Periodicals, Inc. Psychol Schs 43: 143–148, 2006.
