Using a sample from the Korean Education Employment Panel(KEEP), the purpose of this study was to investigate academic achievement of academic high school students. Because academic achievement is affected by many types of contexts and variables, we are limited in how simply we can explain it. Therefore studies related to academic achievement are continuously being carried out according to different variables and subjects. This study examines how the traits of FAMILY, SCHOOL, TEACHER and STUDENT influence ACADEMIC ACHIEVEMENT and what their casual relationships are. The point of this study was to carry out comparative analysis of academic achievement of cognitive and affective outcomes. To define the variables that affect the academic achievement, I selected 5 latent variables(FAMILY, SCHOOL, TEACHER, STUDENT and ACADEMIC ACHIEVEMENT) and 13 observed variables. I used the SPSS and LISREL programs to analyze descriptive results, correlations, and paths. The findings of the study will be a framework for the understanding of structure for academic achievement.
