Pros & Cons of a National Curriculum | Who Decides? An Ideal Curriculum | Democracy, Diversity & Equality Who decides on the curriculum now? Currently there is no national curriculum, but big states drive publishers to write textbooks whose contents cater to their state's needs.

This forces smaller market states to modify or supplement publishers' texts to address their own standard course of study.
