This study attempted to derive and compare the trend of Korean school students' participation in private education of general subject by applying latent profile analysis to the private education survey data of 2011, 2016, and 2021. The results are as follows. First, in 2011, elementary school students were classified into profiles of ‘English Focus’, ‘English & Math Focus’, ‘Comprehensive Participation’, ‘English, Math, & Essay Focus’, and ‘Passive Participation’. In 2016, ‘Comprehensive Participation’ and ‘English & Essay Focus’ profiles disappeared but instead, ‘Korean, English, & Math Focus’ and ‘Other focus’ profiles appeared. In 2021, profiles of ‘English & Math Focus', ‘English, Math, & Essay Focus’ and 'Passive Participation' were derived. Second, in 2011, middle school students were classified into ‘English & Math Focus’, ‘English, Math, & Essay Focus’, ‘Korean, English, & Math Focus’, ‘Comprehensive Participation’, and ‘Passive Participation’ profiles. In 2016, ‘English & Math Focus’ profile was subdivided into ‘English & Math High Expenditure’ and ‘English & Math Low Expenditure’ profiles, whereas ‘Comprehensive Participation’ disappeared. In 2021, ‘English & Math High Expenditure’ and ‘English & Math Low Expenditure’ profiles were integrated into ‘English & Math Focus’, and ‘English, Math, Humanities & Sciences focus’ profile emerged. Third, High school students in 2011 and 2016 were classified into ‘English & Math High Expenditure’, ‘English & Math Low Expenditure’, ‘Korean, Math & English Focus’, ‘Math Focus’, and ‘Passive Participation’. On the other hand, in 2021, the ‘English & Math High Expenditure’, ‘English & Math Low Expenditure’ profiles were integrated, ‘Math Focus’ profile disappeared, and 'Comprehensive Participation’ profile emerged. The results of these studies imply that the trends in private education change according to time and changes in policy, and flexible measures are needed to respond to these changes.
