A manual for assessing the effectiveness of a secondary school, taking differences in the school's resources into account, is presented. The Pennsylvania State Board of Education established the Bureau of Educational Quality Assessment which developed a measurement package in Phase I. Field tests were conducted on grade 11 students in 1968 in 100 pilot schools in Phase II. Students were tested on progress in relation to 10 educational goals adopted by the state, and the schools were stratified according to building enrollment and average per-pupil expenditure for education. The ten educational goals identified were Self Understanding; Understanding Others; Basic Skills-Verbal; Basic Skills-Math; Interest in School; Citizenship; Health Habits; Creative Potential; Creative Output; Vocational Development; Appreciating Human Accomplishment; and Preparing for a Changing World. The actual assessment of the schools began in Phase III. The assessment includes information on pupil achievement, teacher questionnaires, a school information form filled out by administrators and the Bureau of Statistics files. Predictions are made of what performance should be expected of students by using regression analysis of school condition variables. Schools are then rated according to how the student achievement relates to the predicted scores. (DJ)
