@ucbalumnus as far as the UCB COE CS vs. UCB LS CS study - I linked that study as well. I am not really sure, though, that I completely agree with Mr. Kwan’s (a UCB CS alum '16, I believe) conclusion/characterization of the data.
in UCB COE CS&E for 2007, 204 women applied, 58 were admitted, 23 SIRd. (Yield of 39%)
in UCB COE CS&E for 2014, 937 women applied (4x), 101 were admitted (2x), 32 SIR (1.5x). (Yield of 31%)
For UCB COE CS&E the yield has only gotten as high as 45% and is usually below 35% for women.
for UCB LS CS in 2007 36 applied, 17 admitted, 5 SIRd. (yield of 29%)
for UCB LS CS in 2014 470 applied (13x), 126 admits (7.5x), 62 sir (12x) (yield 49%)
For UCB LS CS the yield has not dropped below 35% since 2009 and only gotten below 40% once since then.
So, by 2014, UCB LS CS, despite only 470 applicants, accepted 126 women and enrolled 62. For that same year, UCB COE CS&E received 937 applicants (2x LS CS), accepted 101 of them, and enrolled only 32. Twice as many applicants, half the number enrolled.
Despite starting lower the yield quickly became consistently higher in UCB LS than in UCB COE. After 2009, yield was constantly higher. (and on a general upward trend.) UCB COE (the first number) yield has been flatlined - and even dropped a bit.)
2007 - 39 v. 29
2008 - 20 v. 25
2009 - 46 v. 42
2010 - 35 v. 43
2011 - 30 v. 36
2012 - 26 v. 43
2013 - 25 v. 42
2014 - 29 v. 48
2015 - 32 v. 49
I think those difference are quite interesting.
