The modern system of English medium education was introduced in 1961 and the curriculum reorganized to accommodate the General Certificate of Education, London. Under this system pre-school, primary and secondary education were made available to a large part of the population. The first 'A' level school, The Science Education Center was established in 1987 and an Arabic Islamic Education center was established in 1981. Today, however, primary and secondary education is available throughout the country and primary education is compulsory. As the modern English-medium school system expands, the traditional system is gradually being upgraded.
