It was only in the 1960s that roads were built in Bhutan and Thimphu when the Third King of Bhutan took the initiative after receiving education in it. Prior to that, education was limited to monastic teachings in monasteries, except for a few privileged people who went to Darjeeling to receive western-type education. Dzongkha is compulsory in all schools. Schools are co-educational and education is not compulsory but school education is virtually free. Now, education has spread to all parts of the country. Thimphu has several educational institutions from schooling level to the college level in several disciplines. There are more private schools in Thimphu than in any other place in Bhutan, which are all under the control of the Department of Education. The National Training Authority administers three technical institutes.
