Teachers' contribution in the process of improving the contemporary school performance is manifold and permanent. This study elaborates the contribution of the Kosovan teachers towards the improvement of the quality of work in primary and lower secondary school. Data were collected from 1080 teachers working in schools located in different areas in Kosovo. The data processing was done through the descriptive statistics method with the aim of extracting the characteristics of the data (average standard deviation) and the inferential statistics method in the function of the validity scale of assumptions that result from the data. The research results indicate that today, the Kosovan teachers enjoy more opportunities to influence the policies for the functionalisation and improvement of the work at school, whereas teachers with a higher level of education are more sceptical concerning the issues of influencing the policies of functionalisation and improvement of the work at school.
