Today, the system of Arabic and Islamic education has grown and further integrated with Kerala government administration. In 2005, an estimated 6,000 Muslim Arabic teachers taught in Kerala government schools, with over 500,000 Muslim students. State-appointed committees, not private mosques or religious scholars outside the government, determine the curriculum and accreditation of new schools and colleges. Primary education in Arabic and Islamic studies is available to Kerala Muslims almost entirely in after-school madrasa programs - sharply unlike full-time madaris common in north India, which may replace formal schooling. Arabic colleges (over eleven of which exist within the state-run University of Calicut and the Kannur University) provide B.A. and Masters' level degrees. At all levels, instruction is co-educational, with many women instructors and professors. Islamic education boards are independently run by the following organizations, accredited by the Kerala state government: Samastha Kerala Islamic Education Board, Kerala Nadvathul Mujahideen, Jamaat-e-Islami Hind, and Jamiat Ulema-e-Hind.
