The Spanish Universities Act requires that, for the recruitment by public universities of post-dissertation doctoral teaching assistants and non-civil servant tenured lecturers, preliminary positive assessment of their activity by the National Agency for Quality Assessment and Accreditation of Spain or the external assessment body established under the law of the Autonomous Community is necessary.
The Spanish Universities Act also calls for at least twenty five percent of the teaching staff at private universities to be holders of a PhD degree and to have obtained positive assessment of their teaching and research activity by one of the aforementioned bodies.
