Bilingual education is getting great achievements because of the performance of bilingual programs. In Spain, these programs have been developed at the university thanks to the efforts made during the previous decades of their implementation. The autonomous region of Extremadura has been working cooperatively with other institutions since then, and now it is time to look back to recapitulate what has been done and what needs to be done from now on. This chapter aims to gather the main milestones of this process in order to review its internal and external aspects, as well as to reconsider the ways of improving bilingual programs. Final remarks show that bilingual programs have brought benefits, but there are still some aspects that require attention, such as a homogeneous national regulation or minding the methodological qualification of bilingual teachers. These issues need to be addressed in future research for the welfare of bilingual education.
