The purpose of this study was to compare the effectiveness of the Raven's Standard Progressive Matrices, the Naglieri Nonverbal Abilities Test (NNAT), and the Iowa Test of Basic Skills (ITBS) in selecting for ethnically diverse students who may be gifted. The participants of the study were 175 students enrolled in Grades 3-5 and Grade 8 in a Midwestern school district serving a small city of approximately 40,000 and surrounding rural areas. The results of this study indicate that the Raven's, the NNAT, and the ITBS are not equally effective in selecting potentially gifted children. It is recommended that the Raven's Standard Progressive Matrices be considered as one of the methods employed by a district to select for children who would benefit from gifted programming. While the Raven's is not bias free, the proportion of ethnically diverse students was greater for the sample used in this study than the other two tests. (Contains 3 tables and 1 figure.)
