A recent study of the factorial structure of the Rhode Island Pupil Identification Scale (RIPIS), a pupil behavior‐observation scale for use by classroom teachers for detecting young children with learning problems, has led to profile scoring. This study describes the procedures and the results of an intensive and comprehensive investigation of the homogeneity of the subscales and their reliabilities as well as those of the two profiles yielded by the scale. All subscales, profiles, and composites were found to be highly internally consistent and stable over a time interval of five months. The authors also wish to show why complex psychometric scales require that more than cursory attention be paid to reliability issues.
