This is Groton info from let year’s cycle that I cam across and thought was interesting:
"There were 1,181 applications submitted in total this year, which was a 2 percent increase from last year’s 1,154. Similarly, there was a 3.5 percent increase from 142 admitted students in 2013 to 147 this year. Groton’s selectivity was a little over 12 percent.
The applications came from 22 states and 15 countries, 52 public schools, 87 private schools, and 8 parochial schools. The number of full paying U.S. applications has been fluctuating over the last three years: 352 in 2012, 337 in 2013, and 345 in 2014, as was the case for full pay international applications: 259 in 2012, 328 in 2013, and 318 in 2014.
Out of 518 applicants who requested Financial Aid, 50 were accepted, whereas 97 students out of 663 full-pay students were accepted."
This was the only place in all the info I came across while researching schools that specifically addressed the admit rate differences between FA and FP applicants
