The purpose of the Florida KEY is to provide teachers with a single instrument to infer self-concept as learner of students in grades 1-6. The KEY identifies selected behaviors of students who seem to possess positive and realistic self-concepts in the area of school success. The KEY contains 23 interrogative items that describe student behavior in a classroom. Factor analyses have supported the original factor structure of relating, asserting, investing, and coping. Each teacher completes the Florida KEY in relation to each student. Each item of the KEY is rated in accordance with a 0-5 point scale. Low scores on any of the four factors may indicate students at risk who require the teacher's assistance. Validity, reliability, and factor structure studies of the KEY are described. (BW)
