In 1977, as part of a statewide education reform in former Yugoslavia, the School was merged into the streamlined secondary education (in Serbian: "srednje usmereno obrazovanje"), thus cancelling many, but not all, specifics and advantages over other schools. At that time principal, Milan Raspopović was desperately pulling strings in scientific and policy-making community to re-establish special status, special rights, special funding, and special curriculum. As a result, eleven years later, in 1988, the School was officially re-established as a specialized school, this time in the form of experimental education institution. New curriculum was officially published in 1989, in Official Gazette of Socialist Republic of Serbia, no.2, 15 April 1989.
