The outlier status of caltech's international renown makes it difficult to compare apples to apples with comparatively provincial HMC. It's a bit like trying to compare Bard or Reed or Cooper Union with NYU. So this makes it difficult to compare based on acceptance rates because Caltech will draw a great many more applicants, and consequently turn down a higher percentage. So the acceptance rate of Caltech at around 3%, and HMC at around 13% gives us an idea of how selective they are, but this is confounded with how famous they are - a term thats hard to quantify and control for.

However the graduation rate tells perhaps a (slightly) more nuanced story about rigor. HMC, despite beimg more expensive to attend than Caltech, had a lower 2023 graduation rate of 91.5% vs Caltech at 93.7%

it's not that different, and probably you can construct error bars that enclose both of these bounds within plausible parameters, but it suggests that there is a somewhat higher premium for failure of those actually accepted at HMC than even the mighty Caltech, and a greater willingness to uphold standards at the expense of angering (relatively) wealthy parents.
