The education system is responsible not only for the communication of knowledge, but also for the broadcast of values and accumulation of competence. Requirements to the modern education system are quite antagonistic. On the one hand, education, especially secondary education, should form a certain “standard” — a comparable and similarly verified set of knowledge. On the other hand, a person can change careers, and even professions several times in his or her lifetime, making thus the value of a certain skill higher than that of abstract knowledge.
