The exploratory application of educational indicators originates from the successful demonstration of these economic indicators widely used in the 1970s. Through an abundance of academic research and many practical trials, the OECD is spearheading the concept of economic indicators, i.e., the application of the mechanism of supply and demand in the economic market, into a brand new venue for the field of education. Each indicator is in effect transformed into a factor, either in supply or in demand. Through this transormation it shows the educator and the public a novel picture of how each indicator affects our daily decisions concerning education, and how policy makers could make these decisions. Furthermore, to manifest the importance of tertiary education, the OECD has chosen several indicators to explore the value of diverse and further education. By acquainting ourselves with the facts of where the developed countries are heading in their educational studies, we will certainly broaden our viewpoints on the concept of educational indicators.
