I have posted this in another thread, but wanted to consolidate here, in case anyone wanted to comment. All of this is pure speculation, so please treat it that way
Assumptions
*
Here were the # of ED applications for the Ivy league for the class of 2020
Brown: 3,030(9.3% of total pool)
Columbia: 3,520 (13% of total pool)
Cornell: 4,882 (10.85% of total pool)
Dartmouth: 1,927 (9.32% of total pool)
Harvard: 6,173 (15.8% of total pool)
Penn: 5,762 (14.8% of total pool)
Princeton: 4,229 (14.4% of total pool)
Yale: 4,662 (14.8% of total pool)
Overall Ivy: 34,185 ED/SCEA apps (12.5% of total pool)
If you remove the SCEA schools, the total ED apps for Ivies was 19,121 (11% of their total pool).
Average early admit rate for Entire Ivy pool was 20%. If you remove the SCEA schools, the average admit rate for ED was around 23%
UChicago got 31,411 apps for the class of 2020. So if it mirrors Brown or Dartmouth it will get around 2,900 ED1 apps. If it mirrors Cornell, it could get around 3,100 apps. If it mirrors Columbia or Penn it could get 3,800 ED apps.
Based on that my ED1 predictions are as follows
ED1 Apps: 3,500
ED 1 Admit rate: 23%
ED 1 Yield: 95%
ED 2 Apps: 2,500. This is the hard one to estimate. of around 34,100 students applying ED/SCEA to the Ivies, 80% were either denied or deferred. That is around 27,000 applicants in limbo who were ready to take a leap on ED for the Ivies. I am assuming that less than 10% will now apply ED2 to UChicago because they get nervous.
ED 2 Admit rate: 15% ( I am assuming a smaller admit rate, because I think this pool will be very strong)
ED 2 Yield: 95%
For EA if you assume like the most current year, approximately 12,000 apps were in the EA pool and remove the ED1 number from them, you get
EA Apps: 8,500
EA Rate: 6% (based on the fact that the two ED pools, will mean higher yield)
EA Yield: 70% (Assuming, that the RD yield is rather poor at around 45%, Chicago’s EA yield to fill the 1600+ seat for the class of 2020 must have been pretty high, to give an overall yield as officially stated of 66%. I am taking a conservative number of 70%)*
That means UChicago will already have firm enrollment of close to 1,200 from these ED1 and ED 2 pools alone.
Given a total class strength of around 1,600 or so, there is not much more room left for either the EA pool or RD pool. If they get around 350 from the admitted EA pool, that would bring the total enrollment to 1,550. That leaves next to no room for the RD pool. I expect the admit rate to be dismal for this pool. I mean it could be in the 1%-3% range
That gives an incredibly high yield for Chicago. Over 80% easily. If things go crazy in the ED2 pool, it could be as high as 90% overall!!
I think with the ED1/ED2 strategy, UChicago is trying to mimic the yield and admit rates of Stanford and Harvard. Remains to be seen if they will succeed.
