The purpose of this study was to examine the wage changing on an annual basis. Also, it analyzed how the 1st year Disabled Employment Panel Survey data"s predictive variables influence the wage change. The 1st~5th Disabled Employment Panel Survey data was analyzed by the latent growth model. As a result, the linear change model was the most appropriate for every type verification. The wage has been increasing for the past 5 years. Also, according to the 1st year"s data, higher wage meant slower increase in a long term. The analysis of the condition model showed that male had higher first wage levels compared to the females. Also, the wage increase rate was fast and the age did not have any effect on the wage increase rate. Older ages resulted in slower income increase rates. Also, severly disabled ones had lower income levels at first compared to less severe people. However, the speed of wage increase was not satistically significant. Also, the existence of a regular job position, long job history, high educational level (college graduate) resulted in high income level at first. However, it did not have any significant effect on the increase rate. Finally, the full time jobs and big companies with many employees showed high income levels at first, but the income increase rate became slower after a certain time. The labor union existence and regular(non-temporary) job positioning lead on to higher income level at first but it did not change the speed of income changing rate. In conclusion, the confirmed income level at the beginning was important. Also, the importance of preserving the women and elderly disabled people"s wages have been proposed through the research.
