This document provides a historical overview of studies conducted on the Philippine education system from 1925 to 2012, which found inadequacies in the basic education curriculum. It then outlines the key features and implementation timeline of the K-12 basic education reform launched in 2012, which extended the K-6 elementary and 4-year high school system to include 2 additional years of senior high school. The reform aims to enhance the curriculum, offer specializations, and better prepare students for higher education or the workforce. However, some argue the reform will increase financial burden on families and government without necessarily improving education quality.
