This study was to provide the way of improvement based on the present state and problems of placement project on elementary school sport instructor. "The placement project of sport instructor" was started as the name of "Physical education assistant instructor" in 2008 and it assigned 1,500 sport instructors to 5,800 elementary schools and planned to assign 25,000 sport instructors by 2015. Even though it was developed quantitatively, there have been various problems such as part-time(10 months) contract, payment freeze, heavy workload, inadequate treatment, limited placement, lack of communication system, and so forth in this project. Therefore, in order to maintain health of elementary students, there is the need of specific ways to improve placement project on elementary school sport instructor. The ways to improve the project were as follows: Firstly, extension of government budget on this project and balanced budget should be decided as the policy. Secondly, contract period needs to be extended from 10 months to 12 months. Thirdly, specific wage system and improvement of working condition are needed for sport instructors. Finally, cognition of sport needs to be extended to students and parents as well as physical education. 5 work days as week, increase of working parents, decrease of overweight children are the reasons for maintaining and extending the placement project of sport instructor. Developed infrastructure construction in physical education of school through the placement project of sport instructor will make elementary students healthier mentally and physically.
