The pesantren curriculum is a strategic element in determining the direction, quality, and character of Islamic education. Amid the demands to strengthen the quality of learning and ensure curriculum relevance in the 21st century, pesantren are faced with the challenge of developing adaptive curricula without losing their Islamic identity. This article aims to conceptually and analytically examine the curriculum of Al-Ittifaqiah Islamic Boarding School in Indralaya from the perspective of Curriculum and Instruction studies. The study employs a qualitative approach in the form of library research. The primary data source consists of the official curriculum documents of Al-Ittifaqiah Islamic Boarding School in Indralaya for the 2024–2025 academic year, which are analyzed using content analysis techniques and a conceptual curriculum approach. The findings indicate that the curriculum of Pondok Pesantren Al-Ittifaqiah is built upon a holistic Islamic education framework, integrating diniyah education, Qur’anic memorization (tahfizh al-Qur’an), and formal education, while implementing learning approaches oriented toward character formation, mastery of academic competencies, and the internalization of values. This curriculum demonstrates strong relevance to contemporary Curriculum and Instruction paradigms, particularly in the development of integrative and values-based curricula. This article contributes to enriching the scholarly discourse on pesantren curricula and offers a conceptual model for contextual and sustainable pesantren curriculum development.
