Absolutely. However, because of the current issues there are a lot of politics involved in education, so it's hard to change anything. For example, even if you wanted to implement a "random" system, which is objectively superior for most parents (who wouldn't get in otherwise), it would be shot down quickly.
Similarly, a nation wide curriculum would be shot down because it would make school way more difficult for a lot of parents' kids.
Given that university is becoming the new high-school, is there merit to the idea of just having all universities follow the same curriculum and standardised assessments and exams? Like the University of California system, but nationwide - if not international.
