Several Soviet educational entities are credited in some measure to Pokrovsky's influence. These include the "workers' faculties" "(rabfaki)" established to provide college preparatory education for factory workers to allow their admission to higher education without having graduated from the formal secondary education process. Pokrovsky was also instrumental in the establishment of the Institute of Red Professors (IKP), a de facto graduate school for the advanced training of historians, economists, philosophers, jurists, and natural scientists. He was head of the IKP from 1921 to 1931.
