The purpose of this study is to examine the impact of the perceived support of Career Education on career adaptability activities as an undergraduate student and not falling into a NEET after graduation. Data were from the 2019 Graduates Occupational Mobility Survey (2019GOMS). A total of 5,663 graduates from 2-3 year colleges and 4-year universities who were under 30 years old were finally analyzed employing descriptive statistics, exploratory factor analysis, and SEM. Perceived college support of career education and career adaptability activities as a student were set predictor variables, and falling into a NEET was set as an outcome variable. The path coefficients between latent variables of the hypothesized model were calculated. The findings suggested that the model fitted the data well; that perceived college support had a positive impact on career adaptability activities. Career adaptability activities showed positive impact on preventing graduates from falling into a NEET. Based in the findings, implications for career education in higher education institutes and career preparation behaviors as a student are discussed.
