Purpose - European study quality improvement process is encouraged by the aspiration of European countries to implement the Lisbon Strategy based on Bologna Declaration (1999), the Copenhagen Declaration (2002), the Berlin communication (2003) and other documents which generally requires University to take responsibility for the studies and research quality. The purpose of this paper is to characterize a designing and implementation of a University internal study quality management system elements, exploring how these elements was constructed and used for a study quality improvement. Methodology/approach - The methodology is based on a case study carried out through the analysis of the designing and implementing University internal study quality management system. Findings - This paper is based on a general framework of theoretically well - grounded constructs that could provide researches and authorities of universities deeper understanding of the internal study quality management system improvement practic s and presents the results of the EU funded project “The improvement of internal quality assurance system at Kaunas University of Technology”. These results reveal how the university study quality management system integrates different requirements of the Standards and Guidelines for Quality Assurance in the European Higher Education Area (ESG), EFQM Excellence Model, process management practices, the SA 8000 standard for social responsibility and other quality management tools/ techniques. Research limitations/implications -The results of case study are substantiated by the analysis of one case however; these results could be useful for all Universities. Originality/value - Based on the case study results, this study proposes a general framework of theoretically well - grounded constructs that could provide researches and Universities authority□s deeper understanding of the internal study quality management system improvement practices.
