Based on an exhaustive study from 2001-2003 involving 14 high schools in the EU, a definition of the educational content and the aligned methodology for high school levels was developed for two areas--cyber safety and cybersecurity--with the aim of improving the knowledge and skills of students and their teachers. Available sources, including video platforms, quizzes, presentations, educational games and hands-on sources for practical exercises, were evaluated and included in the developed fiches with educational content. The paper describes the results of the study based on the evaluation of the acceptance of the method and the content by the students and with an assessment of the achieved learning outcomes.
