In this paper, we estimate the wage structure of Japanese care workers, using micro datasets from the survey of care workers (Kaigo Rodo Jittai Chosa). We focus our discussion especially on the impact of acquiring a certificate of qualification and the department from which the person graduated on wage determination. In estimating our function, we consider two dummy variables in addition to the independent variable of education level (high school, junior college, college). One is whether the care worker graduated from the department of health and welfare. The other is whether the worker acquired any certificate of qualification as a care worker. As a result, we found that the college wage premium is observed across care workers. Also, when we focus on those who are graduates from college, being a graduate from the department of health and welfare leads to a premium in wages. However, the effects of these two premiums are decreased by controlling for the acquisition of a certificate of qualification. We also found that among various types of qualification certificates, those for certified care workers, grade 1 home-visit caregivers (popularly known as home helpers), and long-term care support specialists have especially strong correlations with wages.
