yes, confirmed. Those numbers are straight from the FAA. 6825 applied. the system automatically booted some out, leaving 6377. HR went an extra step and qualified 3168 of the 6377. due to negative media coverage and politics regarding the BQ(which qualified applicants without HR going through them), the FAA did away with it, and the FAA knew they would have to manually qualify applicants, so they cut off the bid posting early. normally about 10,20,30ish thousand apply and the FAA didn't want to go through that many applicants.
edit: the FAA says supposedly they can only put 1400 through the academy per year(not to be confused with how many they can hire per year) in 2016 they selected 3027(basically two years worth), last year they selected 1277. im guessing around 15-20% wont show up for the test, considering the last few years 30% didn't ever test. and another couple hundred wont pass at all, so yeah they MAY take all the passes, then again they may be picky and take very few...they might take less now and next year hire for 2 years worth. you never know.
