Under the consideration of fair allocation of nation-wide educational resources, the Ministry of Education (MOE), ROC has been preparing the budget for the private colleges in Taiwan annually since 1980’, and has set subsidy regulations in order to sustain the development of these colleges. Along with the more emphasis on student affairs, MOE’s budget of student affairs for private colleges is also getting more and more. The purpose of this study is to explore how private colleges in Taiwan prepare their student affairs budget and how they control the implementation of the budget during 2003-2006, surveying the school members who are actually responsible for the use of the fund. The result showed that among colleges’ annual sources of the student affairs budget, subsidies from MOE and the schools’ match-up outlays had the major proportion. And the proportion that subsidies from MOE and the schools’ match-up outlays were the colleges’ annual only sources of student affairs budget was increasing annually. Approximately 80% surveyed reported that there was no regular “administration fund” prepared in the student affairs departments at school. For the possible problems in student affairs budget preparation and budget implementation control, “can’t sufficiently understand the regulations about how to use fund of student affairs” had the highest proportion (30.2%) annually. The proportions for the rest possible problem items were: 12.5% “schools fail to establish the conference mechanism to discuss how to use the fund of student affairs”, 10.4% ” schools fail to set proper rules and regulations about how to use the fund of student affairs”, 7.3%” student affairs departments fail to implement annual student affairs budget effectively”, 6.3% “the communications between student affairs departments and accounting departments need to be improved”, 5.2%” top management levels set too many regulations about how to use the fund to student affairs”, and 2.1%” schools fail to establish proper control mechanism of student affairs fund.” The proportions that the funds of student affairs were “for student affairs departments’ exclusive use” were significantly increasing. The proportion that there was no specified unit or people at school designed to handle student affairs budget control was getting more, and the same was for the proportion that there was no regular review on student affairs budget control. Besides, over half reported that at their school the “digesting the budget” phenomenon really existed in the implementation of student affairs budget.
