Hmmm, I just checked the latest from one of our relatives’ Catholic high school (very high performing, rather not say which one) and 28% of the class that just graduated are starting at Catholic colleges this semester, including 7% to Georgetown, 5% to Fordham, 4% each to Boston College and Holy Cross, and 2% to Notre Dame.
I do think there is some special consideration by the Catholic colleges if you go to a Catholic high school even above and beyond the “fit” questions.
