Java's Islamic Boarding Schools, Built Around a Kyai

A pesantren is a traditional Indonesian Islamic boarding school, most closely associated with Java, in which students called santri live communally on a residential compound, the pondok, under the authority of a kyai, a religious scholar who is typically also the school's founder and effectively its head in a single, personally embodied role rather than a role separated from the founding figure. Instruction centers on kitab kuning, literally yellow books, classical Arabic texts of law, theology and Quranic exegesis studied through direct line by line reading with a teacher, often glossed in Javanese or Malay in the margins, a method that has changed relatively little even as the surrounding curriculum has broadened.

Dhofier's study of the pesantren tradition describes the kyai's personal authority, rather than any institutional charter, as the real organizing principle of a pesantren, so that the character and reputation of a given school tracks the standing of its kyai and often struggles to survive his death unless a successor of comparable stature takes over. This structure has made the pesantren the institutional heartland of Indonesia's traditionalist Sunni current, associated above all with the Nahdlatul Ulama network, as distinct from modernist Islamic educational reform movements that arose alongside it in the twentieth century.
