In the era of growing environmental crisis it is necessary to revisit the relationship man - environment. An urgent need has appeared for a change of thinking, as well as evaluating things, leading to changes in attitudes towards the natural environment, which will allow for the survival of mankind. It is currently a very serious challenge faced by modern education – known as pro-environmental education. This task has been implemented also in Poland since the introduction of the reform of the education system in 1998. All the educational efforts would not be possible without setting out a target of education - without proper evaluation. Therefore, the author of the publication focused on the diagnosis of the nature of evaluation by the participants (actors) in the process of ecological education in Polish schools, based on their own research carried out in the area of the Bialski county. This diagnosis may in fact provide important indications concerning the relationship of these persons with the natural environment, and hence the factors influencing the effectiveness of educational interactions in this scope.
