The government of independent Ukraine implemented policies to broaden the use of Ukrainian and mandated a progressively increased role for Ukrainian in the media and commerce. The most significant was the government's concerted effort to implement Ukrainian, as the only official state language in the country, into the state educational system. Despite the Constitution, the "Law on Education" (grants Ukrainian families (parents and their children) a right to choose their native language for schools and studies) as well as the Law of Languages (a guarantee for the protection of all languages in Ukraine) the education system gradually reshaped from a system that was only partly Ukrainian to the one that is overwhelmingly so. The Russian language is still studied as a required course in all secondary schools, including those with Ukrainian as the primary language of instructions. The number of secondary school students who received their primary education in Ukrainian grew from 47.9% in 1990–1991 (the last school year before Ukrainian independence) to 67.4% in 1999""Annual Report of the Ukrainian Parliament Commissioner for Human Rights “On the situation with observance and protection of human rights and freedoms in Ukraine” for the period from April 14, 1998 till December 31, 1999" "</ref> and to 75.1% by 2003–2004 (see table). Ukrainization has achieved even greater gains in higher education institutions where as of 1990-1991 only 7% of students were being taught primarily in Ukrainian. By 2003–2004 the percentage of college and technicum students studying in Ukrainian reached 87.7% and for the students of the University-level institutions this number reached 80.1% (see table).
