In contrast to cognitive skills, non-cognitive skills play a key role in shaping an individual's life course, yet the development of non-cognitive skills attracts insufficient attention. This study explores the contribution of study halls today to address the social disadvantage inherited by students in the area of non-cognitive problem-solving skills. The results of our exploratory study in five study halls in cities with county status in the Northern Great Plain region showed that study halls play a prominent role in mitigating the skills deficits of the mainly upper primary disadvantaged students included in the study. As a result of the developmental work of the study hall, problem-solving skills showed improvements mainly in the reduction of problem sources, in the problem-solving instruments and in the form of problem solving. As a result of the intervention of the study hall, the students' acquired social disadvantages were reduced and their inclusion in school, later in the labour market and in society was reinforced.
