The subject of this research is the existence of a correlation between two significant variables, namely students' assessments of traditional folk music and knowledge in this area, but also between crossed variables of assessments of different components. The research was conducted on a sample of N=205 fifth-grade students from three elementary schools in Banja Luka. Research has shown that students' assessments and knowledge are related in almost all parameters, except folk instruments and composers, whose correlation is not statistically significant. Also, the hypothesis that there is a connection between all parameters of assessments of folk music tradition (traditional folk songs, folk instruments, musical dances) as well as with popular children's songs was fully confirmed. Actively dealing with traditional musical content as well as new research will shed light on the importance of the presence of folk music tradition in elementary schools.
