Performance evaluation of compulsory education system in Taiwan: A modified dynamic network data envelopment analysis approach

The purpose of this study is to examine changes in the efficiency of Taiwan's compulsory education system between 2011 and 2020, identify the priority school sub-system for improving the system, and determine the input/output inefficiencies responsible for the sub-system inefficiencies. To achieve these objectives, a modified dynamic network data envelopment analysis model is used to assess the efficiency of the compulsory education systems and their internal primary and middle school sub-systems regulated by local governments. The findings indicate that both primary and middle school efficiency are crucial for evaluating the compulsory education system efficiency, and teacher and staff excesses in most local government's compulsory education systems are the primary sources of inefficiency. Therefore, the prompt adjustment of teacher and staff allocation based on student numbers is the primary approach to enhancing system efficiency.
