The purposes of this study were to understand (a)the effectiveness, strengths, and weaknesses of the dropout-prevention programs implemented by all the local governments, (b)the accountability of the alternative education programs implemented by the local governments, and (c)the status, dilemma, and limitations of the dropout-prevention programs in Taiwan. The study was conducted by evaluating dropout-prevention programs at 25 counties around the nation. Firstly, the researchers reviewed related literatures to identify the dimensions and detailed indicators of evaluating dropout-prevention programs in order to develop initial evaluation tool. Then the researchers applied Delphi method to revise the indicators. Finally, the researchers held a work conference, inviting the administrators who were practically in charge of plan and execution of dropout-prevention in the local governments to discuss and modify the initial evaluation tool to develop the formal research tool, Dropout Prevention Inventory─DPI. Data were collected from the Annual Reports of the dropout prevention programs released by the Ministry of Education, the self-report of the administrators in local governments, and the DPI completed by the interviewers to evaluating the dropout-prevention programs in all the local governments. The dilemma and limitations of the dropout-prevention programs were analyzed in according to six dimensions: "Leading, Organizing, Operating, and Planning," "Input and Usage of Resources," "Student-Dropout-Prevention and Programs for At-Risk Student," "Dropout Register, follow-up, and Helping Back School", "Programs for Reentry Students," and "Alternative Schools Programs for Reentry Students." The study provided practically suggestions for the dropout-prevention programs to all the local governments and the central government of and further study.
