Why are US Business School Rankings so Rigid?
If you look at Business School rankings over the past 30 years, there’s almost zero movement at the top.
• The same schools have dominated the M7 for decades.
• Very little change in the T15.
• Same story in T20 and even T25.
This level of rigidity is quite unusual compared to other industries or global rankings.
Questions for the community:
- Is the ranking system so competitive that it’s nearly impossible for schools to break into the top tiers?
- Are there simply no “vacancies” in the T15/T20 — meaning the top schools are too entrenched?
- Have the top schools reached some kind of equilibrium where they’re all performing at a similar high level?
- What would it actually take for a T25 school (e.g., Olin, USC Marshal, Indiana Kelley, etc.) to break into the T15 or even T10?
Would love to hear thoughts from current students, alumni, and admissions consultants. What “extras” do lower-ranked schools need to focus on — research output, employment outcomes, brand building, alumni network strength, or something else?
