Costa Rica can build on its many strengths - including a reformed curriculum and a growing and well-funded vocational system - to make upper secondary education more inclusive. A more systematic approach is needed to tackle disadvantage, and particularly to improve teaching in the schools with the highest levels of disengagement and drop-out. Further support is needed for teachers to implement the new curriculum, and reform the Bachillerato examination to give a fairer chance to students to complete secondary education.
