I suspect the ED1 pool will have lower stats, as they’d include the recruited athletes and unhooked low to medium stat apps looking for a significant boost. However, my guess is that BC will see higher stats in ED2 than ED1. The hard part for the school may be not knowing what the ED2 pool looks like before making ED1 decisions.
BC historically has deferred 30-40% from EA/REA and may do something similar with ED; maybe they’ll defer more from ED1. With what they’ve said about app number projections, it sounds like they don’t think the process will be very different, just that they’ll have fewer to review early.
I’ll be interested to hear more details about the engineering program as they emerge, especially the logistics of attracting students while needing to get accredited. (I have at least one potential class of 2025 kid who may be looking for engineering programs and it sounds like that is the earliest possible class for the new program.)
