The Soviet system was based on the needs of the economy; the agrarian, medical, and polytechnic institutes were all founded to aid the economy. Outside of that, most higher education in the system were in the form of pedagogical colleges. Restrictions on political subjects such as history hampered advancements in those fields. After independence, universities less precisely tailored their courses to the economy and as a result other professions proliferated in schools such as the Tajik University of Law, Business and Politics.
