The different accreditation processes of undergraduate degrees are the object of research due to the value of international recognition based on their accreditation. Thus, accreditation has become the preferred means of monitoring and evaluating the quality of higher education and observing universities' impact on society. The present study is part of a broader research focused on developing a doctoral thesis. It is framed in the qualitative interpretative paradigm of an emergent exploratory type. The main objective is to identify the public value generated by accreditation in the continuous improvement of undergraduate programs accredited by SINAES (an anagram of Sistema Nacional de Acreditación de la Educación Superior, National System of Higher Education Acceditation), in the field of education in Costa Rica. Five in-depth interviews were conducted to learn the perceptions of the key informants who participated in the accreditation process of the six selected degree programs. The results show the public value that accreditation produces in the continuous improvement of Education Degree Programs through ten categories that cover the achievements, benefits, results and effects of the contribution of SINAES in the continuous improvement processes of higher education. In conclusion, accreditation has become one of the determining factors when selecting an Education Degree Program in Costa Rica. The processes carried out by SINAES are perceived as legitimate and of excellence in developing these types of quality certifications.
