Issues concerning access to higher education are seen differently in various European education systems. In some of them, the paths leading to the desired college or university can be wide, in others difficult to reach or very bumpy. Learners of schools for adults represent a particular group vulnerable to difficulties in accessing higher education. For these learners, the accomplishment of the entrance examination requirements is not always equally achievable as for youth schools students. This paper presents the comparison of various approaches to the issue of access to higher education for adult learners in European countries. In particular, it indicates two systems of learners' skills evaluation, similar in way of organization but opposite in obtained results. The first one is Finnish and the second one Polish Matriculation Examination system, regarded as the Entrance Exams to university level education. Both systems are presented in from the perspective of learners of schools for adults, mostly young people who have dropeed out of the youth system. The analyses take into account secondary data from examination sessions 2015-2018, provided by the Polish Central Examination Board and the Finnish Matriculation Examination Board. The main goal of this paper is to indicate the difficulties faced by learners of upper secondary schools for adults, especially in Poland. The difficulties causing that door to higher education are closed in front of these learners.
