The purpose of this study was to standardize the Primary Measures of Music Audiation in Greece (N = 1,188). Split-halves reliability was acceptable across grade levels (K through 3) for the Tonal and Rhythm subtests, but test-retest reliability was generally unacceptable, especially for the Rhythm subtest. Concurrent validity was mixed, with teacher ratings of musical achievement generally significantly correlated with Tonal but not Rhythm subtest scores. Composite test means were significantly higher for suburban and urban samples than for rural samples and were significantly higher for higher grade levels. Item difficulty coefficients were significantly correlated across grade levels. The Greek and U.S. composite means were similar except for a significantly higher U.S. mean for grade 1. However, when the rural subgroup was removed from the Greek sample to equate with the U.S. norming sample, there were nonsignificant differences from grades K through 1, but significant differences in favor of the Greek sample for grades 3 and 4.
