15-year free education has been implemented in Macau and some parts of Mainland China in recent decade. In light of the implementations, local early childhood educators and experts have since been debating whether Hong Kong should follow suit to offer the 3 years of early childhood education (ECE) for free on top of the existing 12-year free education. With reference to the policy implementation and outcomes in Macau and Mainland China, as well as the ECE context in Hong Kong, this paper seeks to (1) delineate the dilemmas in the debate about 15-year free education in Hong Kong; and (2) suggest how free ECE could be offered in a context-appropriate manner. We will discuss the issues based on the “3A1S” theoretical framework, which looks into the affordability, accessibility, accountability, and sustainability of ECE. Practical solutions for settling the ceaseless debate about 15-year free education in Hong Kong will also be proposed.[Copyright © 2014 Hong Kong Teachers' Centre]
