The first part of the two-volume publication summarising the first Erasmus+ perspective. It presents the effects of the program through the eyes of the beneficiaries who implemented projects all over Poland in the years 2014-2020. The interviews are accompanied by descriptions of the achievements of each of the five Erasmus+ sectors as well as accompanying programs and initiatives. Examples of good practices discussed in the book show different ways of using the funds of the largest educational program in Europe, which contributed to the change of the Polish education and to the increase of key competences among students, adult learners, teachers, lecturers and trainers.
