Despite their widespread use in identifying and evaluating programs for gifted and talented students, the Torrance Tests of Creative Thinking were standardized on samples that excluded gifted children. The interrater reliability of measures like the TTCT has been questioned repeatedly, yet studies with average students have demonstrated high interrater reliability. This study compares the interrater reliability of the TTCT for groups of gifted and nongifted elementary‐school‐aged students. Results indicated most interrater reliability coefficients exceeding .90 for both gifted and nongifted groups. However, multivariate analysis of variance indicated significant mean differences across the three self‐trained raters for both gifted and nongifted groups. Consequently, use of a single scorer to evaluate TTCT protocols is recommended, especially where specific cutoff scores are used to select students.
