The Formal Operational Reasoning Test

Educational researchers and psychologists have devoted considerable attention to the measurement of formal operational reasoning abilities. But the lack of suitable paper-and-pencil instruments has limited the quality and extent of assessment possible in regular classrooms and other group settings. The Formal Operational Reasoning Test (FORT) was developed to obviate such problems. Data (N = 300 seventh and eighth grade boys and girls) pertaining to the reliability, content validity, and construct validity of the FORT are reported. It is concluded that the FORT is a reliable and valid measure of formal operational reasoning abilities which is appropriate for use with Ss at or beyond the junior high school level.
