During recent years, the promotion of lifelong learning and the development of a “learning society” have become important goals for Taiwan and many other countries. However, we do not yet have development indicators and ideal index systems which can be used to gauge a society’s degree of “development” in this regard, and thus to judge whether a society has in fact become a “learning society.” The purpose of this study is therefore to construct development indicators and ideal indices for a learning society according to the learning-society conceptual framework and a Context-Input- Process-Products (CIPP) model. Literature review, focus groups, and questionnaire investigation are the three main methods used. The analysis of 4 years of educational statistics (1999-2002) reveals that in Taiwan most educational developments in the direction of a “learning society” do not come up to the expected ideal indices.
