In 2017, the education reform, with structural and curriculum dimension, was introduced in Poland. Middle schools were closed down, eight-year primary schools and four-year high schools were restored, new core curricula were proposed. The proposed solutions were both praised and criticized by various environments. They also launched some parents' activities, protesting against or supporting them. In the article, we look at the activities undertaken by parents in relation to the described reform and we analyze opinions formulated by parents about the introduced change. In our research, we use existing data from parents' associations websites, internet forums and interviews given by parents. The analysis of arguments raised by parents is intended, on one hand, to deepen the recognition of their attitudes towards the reform, and on the other hand, to examine the parents' ideas of what they think the modern school is supposed to be.
