Abstract
The main purpose of this study is to evaluate the technical efficiency of high school education in Indonesia by applying Data Envelopment Analysis (DEA), which is the most frequently used to measure the efficiency scores. However, this study uses a robust approach to face the complex problem of the traditional DEA, which may lead to biased results. Besides, it is a powerful approach to estimate technical efficiency when outliers contaminate the data set. Statistical data from general senior secondary schools in the period 2015/2016 is analyzed, using 34 provinces as decision-making units (DMUs), with eight input and six output variables. The results indicate that the average efficiency score of Indonesia’s major political subdivisions in managing high school education is 0.936. Furthermore, as many as 32.35 percents of provinces achieve efficient performances, with an efficiency score equal to one, while 17 provinces have above average efficiency scores. The results also indicate that efficiency scores from robust data envelopment analysis provide better accuracy. Overall, application of robust data envelopment analysis (RDEA) is appropriate for measuring the efficiency of provincial performance in organizing secondary education.
Highlights
High schools are very important educational institutions because they prepare students to face the real world by providing them with the necessary skills and knowledge to be able to live independently and co-exist in the community in a proper manner
The calculation of efficiency scores using the Data Envelopment Analysis (DEA) method is made for all provinces in Indonesia. 34 provinces are used as decision-making units (DMUs), which are analyzed by using six output variables (O) and eight input variables (I)
This study used robust data envelopment analysis (RDEA) to investigate efficiency measurement when the actual data are contaminated by outliers, as the efficiency scores of traditional DEA are susceptible to bias. 34 provinces were used as DMUs, whose efficiencies were measured by using eight input variables and six output variables to evaluate technical efficiency in managing high school education in Indonesia
Summary
High schools are very important educational institutions because they prepare students to face the real world by providing them with the necessary skills and knowledge to be able to live independently and co-exist in the community in a proper manner. Analysis of the measurement of the efficiency of high school education is important. A robust approach is used to face the possibility of the existence of outliers in the actual data set. This approach tends to provide results with better accuracy. By knowing the efficiency of each province in managing high school education, the Indonesian government is able to determine the best role model of high school management in order to improve the efficiency level of other provinces. This study is expected to make a contribution to Indonesian education, especially high school education, and enhance the quality of high school graduates who are ready to meet further challenges, whether these be college life or going straight to work
