This study aims to reveal the relationship between primary school students' perceptions of self-learning and decision-making skills and whether gender, the education level of parents, and the number of siblings cause a difference. Within the framework of the stated purposes, the correlational survey model, which is among the quantitative research approaches, was used as a method in the research. The population consists of public primary schools' students studying in the city centre of Diyarbakir in the 2021-2022 academic year. The sample consists of 420 students determined by the "Simple Random Sampling" method, which is one of the probability sampling types, among the participants in the population. Descriptive and inferential statistical methods were employed to analyse the data. In the study, it was determined that there was a moderate, positive, and significant relationship between primary school students' self-learning and decision-making skills. In the study, it was determined that the self-learning skills of primary school students differed significantly according to gender and the number of siblings, but did not differ significantly according to the education level of their parents. In addition, the decision-making skills of primary school students were found to differ significantly according to gender and did not differ significantly according to the education level of their parents and the number of siblings.
