The Ministry of Education, Youth, Sports and Library Services oversees education in Turks and Caicos. Public education is supported by taxation and is mandatory for children aged five to sixteen. Primary education lasts for six years and secondary education lasts for five years. In the 1990s the Primary In-Service Teacher Education Project (PINSTEP) was launched in an effort to increase the skills of its primary school teachers, nearly one-quarter of whom were unqualified. Turks and Caicos also worked to refurbish its primary schools, reduce textbook costs, and increase equipment and supplies given to schools. For example, in September 1993, each primary school was given enough books to allow teachers to establish in-class libraries. In 2001, the student-teacher ratio at the primary level was roughly 15:1.
