The impact of the PISA study on Polish education policy has been significant, but probably different from any other country. Poland has not experienced the so‐called ‘PISA shock’, but its education system has been benefiting considerably from PISA. For experts and policy makers, it has been a useful and reliable instrument that has made it possible to measure the effects of consecutive reforms of the school education system. Moreover, PISA and other international studies have influenced the perception of education policy in Poland. The latter has shifted from an ideology‐driven, centralised policy to an evidence‐informed policy, developed with the involvement of multiple stakeholders, although this has mostly affected the thinking of experts and policy makers rather than the general public. The new government (in power from 2015), following public opinion polls, has reversed most of the previous education reforms, eliminating lower secondary schools introduced in 1999.
