S23 applied to a dozen schools, seem to recall only 2-3 of them were 4 year year BA Arch (one was in-state flagship). I’d say the schools were roughly 1/3 each required/rec’d/don’t submit on the portfolio. Completely agree that even if it’s rec’d - submit it, it can only help the applicant.
In hindsight some of the schools he applied to I would have guided him not to bother with (U-Texas, NC State) due to their low OOS admit rates making a reach(y) school unrealistic.
A steep learning curve for sure.
