In recent years major changes have been introduced into the system of higher education in the common European Higher Educational Area (EHEA). On account of the Bologna Process the EHEA is leading to greater compatibility and comparability of the systems of higher education and is making it easier for learners to be mobile and for institutions to attract students and scholars from other continents. In 2011, the Law of the Higher Education (Dz.U. No 84, poz.450) in Poland has implemented the "National Qualifications Framework" (NQF) which assumes that the education in each of the EU countries is transferable and that every student gets the right, with no further conditions, to continue his/her studies in any other country within the community. This article describes the rationale for introduction of the NQF into graphics courses teaching. New requirements set up by the NQF have caused a revision of the curricula at all universities in Poland. Much stress has been put on the load of knowledge, abilities and competences, which resulted in re-formulation of the courses. Delivery of the online content for the undergraduate engineering graphics (DG and TD) instruction in a form of blended courses for over 3 years has been beneficial to the students and it complies with a model of a student-centered education.
