Abstract: In system-level educational monitoring, Indonesian Ministry of Education and Culture publishes statistical data of education every year. The data are used to evaluate the educational development in Indonesia. But when it comes to educational effectiveness, the topic is not yet an issue. Some publications had been discussed about educational effectiveness by focusing on observing the educational substances. Moving from recent effectiveness issue condition, this research is trying to give a different point of view by using educational data from the government to evaluate the educational effectiveness. The hybridization of input-output model and clustering analysis is introduced in this study as a new approach to evaluate the educational effectiveness. As the result of the method’s usage even though it could not explicitly measure the effectiveness rate, the method may estimate the effectiveness relative to all members. Based on the data, it could be inferred that the effectiveness of educational development is 85, 88 and 76% for elementary school, junior and senior high school, respectively.
