Spain has embarked on a continuous reform and adopted new strategies to improve higher education in the recent years. Evaluation has been carried out, the first form 1996 to 2000 and the second from 2001 to 2006. Diverse models of evaluation have been applied to the assessment of teaching, department organization, research and service unit so far. They are carried on the national level and local level as well. This paper aims at studying the system of internal assessment (done by the committee of each university), and especially, at exploring the role of the committee in determining the quality of Spanish universities. By taking the document analysis, we want to present four main characteristics of the reform of Spanish education: (1) the foundation, reform and development as well as the performance (quality) of the assurance system; (2) the evaluation system and the organization of the committee as well as the emphasis on internal evaluation; (3) the strategies taken by the committee of internal evaluation; (4) the suggestions for an improvement of the quality assurance system in university and for administrators.
