		abstract={High efficiency can be the main pillar of bank health. The aim is to re-examine the effect of CAR, NPL, LDR and Company Size on Efficiency Levels. Conventional commercial banks registered on the IDX in 2019 - 2021 are the population used in this study with a total population of 41, a sample size of 40 and there is 1 bank that does not publish annual reports on its website. Thus, the sample data used is 3 x 40 = 120 data. Samples were taken using purposive sampling technique, this type of research is secondary and uses quantitative data. This study uses Data Envelopment Analysis (DEA). Based on the simultaneous results (test statistic f) shows the results on CAR, LDR, and Firm Size have a significant effect on Efficiency. Meanwhile, NPL shows results that have no significant effect on efficiency. Partially (t statistical test), namely CAR has a positive effect on the level of bank efficiency. NPL has a negative effect on the level of bank efficiency. LDR has a positive effect on the level of bank efficiency. Firm size has a positive effect on bank efficiency.}
