Transition from the Soviet type of economy to a new market system showed the necessity in reforms at the secondary school level. Based on a literature review, this paper aims to reveal how the thinking about teaching economics has changed over the past three decades (1991-2021), and how this has affected teaching economics as a school subject in the Post-Soviet countries. The article illustrates these with the cases of Russia and Kazakhstan. For this paper, a narrative literature review methodology was adopted and scanned studies included only those published in English and Russian.
