This study was conducted to measure the relative efficiency of 124 junior colleges in Korea. Data for three years from 2020 to 2022 were provided on the university information disclosure website, and the relative efficiency and productivity changes of junior colleges were analyzed using DEA and Malmquist techniques. As a result of the DEA analysis, it was analyzed that the efficiency of 23 junior colleges in 2020, 34 in 2021, and 26 in 2022 is determined by scale. As a result of the analysis of the Malmquist productivity index, a total of 33 junior colleges have generated technological progress, and 91 junior colleges have generated technological regression, which is about three times higher than the occurrence of technological progress. The average value of MPI-based productivity was analyzed to have decreased by about 4.8% over three years, and it was found to be affected by changes in efficiency. It was analyzed that 108 junior colleges were affected by efficiency by scale, excluding 16 junior colleges that were analyzed to have pure technological efficiency greater than efficiency of scale.
