In our rapidly changing world, the role of education is not only to pass on knowledge, because the acquired knowledge will be quickly expired, the different professions are also changing in a short time. It would be also important to pass on a kind of ability which the students will be able to independently acquire knowledge after completing their studies with or they would be able to navigate safely through the world, or to work in a team. The project-based education is one opportunity to reach this, with many people have been dealing since the mid- 20th century with, but it has not become popular in education. One explanation to this is that the project work is managed in team, hence it is difficult to evaluate well. In my article, in addition to the general description of the evaluation of the project task, I give valid examples of how this evaluation can be applied in education. Considering the importance of project-based education being present in all age group, some of my examples can be used in public education and the other in higher education.
