In 2004, madaris were mainstreamed in 16 Regions nationwide, primarily in Muslim-majority areas in Mindanao under the auspices of the Department of Education (DepEd). The DepEd adopted Department Order No. 51, which instituted Arabic-language and Islamic Values instruction for Muslim children in state schools, and authorised implementation of the Standard Madrasa Curriculum (SMC) in private-run madaris. While there are state-recognised Islamic schools, such as Ibn Siena Integrated School in the Islamic City of Marawi, Sarang Bangun LC in Zamboanga and SMIE in Jolo, their Islamic studies programmes initially varied in application and content.
