This project was aimed to investigate and to predict the outcomes of senior high schools in terms of the distribution of their students' scores obtained in Joint College Entrance Examination and whereby to explore the pattern and characteristics of school stratification in Taiwan. The data for this study included annual report of JCEE in 1992, 1991 and those data collected by a questionnaire administered to student sample of 3775, 90 classes in 30 schools; and a survey scale administered to the school sample of 30 schools, of which 10 from pretigious upper stratum schools, 10 from middle ones, 10 from lower ones. Correlation analyses, and multiple regression analyses were computed on the data collected. Upon which some major findings were as follows. A possibility was confirmed that the students' achievement in terms of their scores in JCEE can be predicted by a multiple regression (1). Taking school history, culture and tradition, (2). Taking students' aptitude and characteristics, (3). Taking students' hom environment variables separately or collectively as predictors. Among those predictions the variance explained is the largest when school variables were taken as predictors. Based on those findings, the study concluded that school cultural theory, school effectiveness theory is more appropriate to explain the variation of schooling success rather than resource distribution theory.
