The reliability, validity, and factor structure of the Charles F. Kettering Scale, an instrument for the development of personnel and programs in schools, were investigated. The 40-item General Climate Factors section of the scale, a measure of educational environment, was completed by 30 administrators and teachers, 78 ninth graders, 66 eighth graders, and 83 seventh graders in a junior high school. Reliability was estimated, and coefficients were given. The Statistical Analysis System principal components program was used to examine construct validity. Five second-order factors represent the eight postulated scales of the instrument. Overall, data suggest that there are five "what is" subscales and three "what should be" subscales. The currently used subscale divisions may be inappropriate. Suggested refinements, including use of a five-point scale and different subscale divisions, may make the instrument more effective for a junior high population. Three tables present study findings.
