This study was designed to illuminate the state of education in Taiwan by constructing Educational Indicator Systems. The study, sponsored by the National Science Council between 1998 and 2000, was the first comprehensive indicator project to cover all educational levels in Taiwan. Various research methods were used, including panel discussion, conference, setting up website, Delphi technique, questionnaires and visits to 14 international organizations and government agencies. In the process, two educational indicator systems based upon the "Context-Input-Process-Progress" (CIPP) model were formulated: "Taiwan's Educational Indicator System by educational level" (TEIS by el) with 99 indicators, and "Significant Indicators of Taiwan's Education" (SITE) with 34 indicators. Finally, some limitations and suggestions were offered for the future development of Educational Indicator Systems.
