The adult literacy rate in 2010 was 86.9%. Before 1970, only three formal schools existed in the entire country, with fewer than 1,000 students. Since Sultan Qaboos' ascension to power in 1970, the government has given high priority to education to develop a domestic work force, which the government considers a vital factor in the country's economic and social progress. Today, there are over 1,000 state schools and about 650,000 students.
