The aim of the present research is to describe the role of the Warmia and Mazury University in the formation of the functional macroregion in the Olsztyn agglomeration. The main criterion used to delimitate the macroregion of Olsztyn is the range of educational services of the biggest university in Warmia and Mazury. The authors use data relating to the place of living of the candidates who registered during the recruitment process in 2011 and 2012. They also analyze the impact of selected factors on the size of the area of Olsztyn university’s spatial influence. The research results show that the functional macroregion of the Olsztyn agglomeration covers, apart from the Warmia and Mazury voivodship, also the neighbouring districts of the Podlaskie and the Mazowieckie voivodships.
