ENSince its independence in 1990, Lithuania has been a country in transition. In particular, it has been moving towards greater integration within the European community. A key element in this has been a commitment to educational reform with the emphasis on improving the quality of education for young Lithuanians so that they, and the country, are better prepared to meet the increased competition that a broad, European market brings. Reform of the curriculum and teaching methods began almost immediately after independence. These were natural starting points. However, it soon became apparent that assessment would also need attention since it forms an integral part of the teaching/ learning process. A system was needed which would be comparable with those used elsewhere in Europe. This required a more rigorous approach to the assessment of student achievement and the measurement of educational standards. The Lithuanian National Examinations Centre (NEC) is a young institution. Established in 1997, it developed a new system of State secondary school leaving (Matura*) examinations and ran them for the first time in 1999. This remarkable achievement was supported by the Ministry of Education and Sciences (MES) and by the European Union's Phare programme for Higher Education Reform in Lithuania (HERIL).This case study is not intended to be a formal, technical report - but rather to tell the story of NEC's growth, its work under the HERIL programme, and some of the lessons learnt along the way. In particular, it attempts to identify the factors that contributed to the success enjoyed by NEC and its partners. We hope that the study will prove of interest, and perhaps of some value, to those working to reform educational assessment systems in Europe and beyond. The authors wish to thank Sabine Seaman (EU Delegation, Lithuania) for supporting the idea of recording, in this way, the experiences of those involved in the Programme, and Simon Peters (HERIL Programme Manager) for his considerable help in making it a reality.
