hi, you might note milton historical acceptance rate is 20 - 25%, but last year maybe a little lower - i think slightly less than 20%.
speciafically, the new enrolled students in milton website (143 new students started in 2012) include those from k8 (maybe 40 - 50) Today's Miltonians
if you include exclude those, then the admission rate fall below 20%
also i just been to milton last week, and was the 2016 class (class started freshman) is the smallest class they had because the year before (2015 class) their yield was much higher than historical. is recently their acceptance rate may be a little smaller than historical (which is 20 - 25%)
