The considerations presented in this paper refer to the idea of developing academic honesty and introducing ethical standards in research among high school students of the International Baccalaureate Diploma Programme. The mission of the International Baccalaureate Organization is to form a better world through education. One of the ways to achieve this is to create international educational programmes that include the development of a respectful, principled and caring attitude among their students. Teaching about academic honesty and ethical standards in research as well as introducing these principles in everyday school life is the best way to put these rules into practice. In the following paper, the regulations of the International Baccalaureate on academic honesty in general and ethical guidance for psychology in particular will be presented, followed by examples of good practice from one of the IB schools, the Międzynarodowe Liceum Paderewski in Lublin, Poland.
