This study was done to evaluate the formal education program provided by the Korean government for care workers for frail elderly people. This study was a cross-sectional survey in which 438 certified care workers who had completed the education program participated. Data were collected from June to October 2009, using a self-report questionnaire consisting of satisfaction with, and understanding of the education program. The participants had a mean age of 46.7 yr, 87.9% were female and 58.2% were high school graduates. For the theory part of the education, the highest score for understanding was for'supporting household & activities of daily living' while the lowest score for understanding was for'care for death and dying'. For the practical education, the highest score for understanding was for'talking with the client' and the lowest score was for'first aid & basic life support'. There was a significant difference in satisfaction and understanding of the theoretical and practical parts according to educational level. Continuing education programs are needed for care workers for elders, both in the theoretical and practical areas. Also the content of programs should address the weak points of this formal education program.
