The spread of formal Quranic school (called ''daara'' in Wolof) during the colonial period increased largely through the effort of the Tidjâniyya. In Murid communities, which place more emphasis on the work ethic than on literary Quranic studies, the term ''daara'' often applies to work groups devoted to working for a religious leader. Other Islamic groups include the much older Qādiriyya order and the Senegalese Laayeen order, which is prominent among the coastal Lebu. Today, most Senegalese children study at ''daara''s for several years, memorizing as much of the Qur'an as they can. Some of them continue their religious studies at councils (''majlis'') or at the growing number of private Arabic schools and publicly funded Franco-Arabic schools.
