Anyway, the top 3 Catholic universities are deregulated by CHED, that would mean they have the freedom to assess their own curriculum or improve more on their current course offerings. Most specially if their courses or colleges were declared as Centers of Excellence or Centers of Development by the CHED.

Yearly, each college of these universities assess their course offerings and check for some loopholes or any relevant amendments they can make to improve it. Say, if the course or subject is still relevant or not. Or whichever is much needed or in demand in the employment industry.

If you need the detailed processes, surely these universities will not divulge to you. Just a matter of idea how. They are working and spending so hard to maintain their status, competitiveness and reputation. It’s trade secret you know. Hope this answer helps you somehow. =)
