The curriculum in the Philippines has evolved over time through different periods of history. During the pre-Hispanic period, education was oral and practical, aiming to prepare children for adulthood. In the Spanish period, friars managed parochial schools that spread Christianity through basic education. The American period established a public school system and abolished religious instruction. Today, the K-12 program provides mother-tongue based education through junior and senior high school, allowing students to choose between academic or vocational tracks.
