The classification of veterans in disability rating is an important system to efficiently implement the policy for patriots and veterans, in that it decides the disability rating according to handicapped degree of patriots and veterans. The purpose of this paper is to improve the classification methodology of the present system through comparative analysis on the strengths and weaknesses of other classification systems of Korea and foreign countries. The analysis on the rating system of the handicapped show a variety of different rating systems. For example, the industrial compensation system in Korea classifies disability degree into 14 ratings and 141 sub-ratings, the compensation system for patriots and veterans in Korea classifies disability degree into 10 ratings and 166 sub-ratings and the US military classifies disability degree into 10 ratings and 1,034 sub-ratings. Also, such systems are named differently and have different medical agencies or organizations to examine disability and decide the rating. The study shows a result that each system classifying veterans' disability degree differs from one another because it uses different rating methods in classifying disability degree. The current classification system of veterans' disability rating still has much room to be improved because, first, Korean classification system in veterans disability rating should reflect the highly advanced medical technology; second, the needs of handicapped veterans for medicare service are daily increasing; and third, clients with disable veterans are still dissatisfied with the present classification system. Then, the current policies can be improved in a variety of ways, by adopting following directions. First, the veterans' disability rating should be classified in line with the development of the advanced modern medicare technology. Second, veterans' disability degree should be classified with a clearer and more equitable method to minimize the unsatisfaction of clients. Third, the AMA methodology of the US should be adopted as early as possible. Fourth, classification methods of veterans' disability degree in Korea should be integrated so as to give people with the same disability degree the same rating.
