Teachers' role in curriculum design is a broad question that inspires political educational reforms among European countries, a trend that even extends to higher education politics. The perspective on teachers' role in curriculum, both at the level of the policies and of the practices, shapes recent educational reforms in Portugal. These are the concerns underlying our research that intends to substantiate school teachers' involvement in curriculum development as it is experienced by them, and while comparing their views to the roles they are attributed in the political and academic dominant discourses. To reach teachers' perceptions, we distributed questionnaires which were completed by 214 teachers in primary and secondary schools. We could conclude that the enactment of a professional identity on the basis of teacher assumption of their role as real curriculum designers is still far from being achieved.
