EA slots are done from a national perspective. HQ AFROTC will be told by AFMPC how many officers will be needed in 2 yrs. That is the number they will use to determine how many slots will be needed. I.E. let's say MPC says 2300 and there are 3600 currently. Every cadet will be awarded a score using their PFT, cgpa, det rank and CoC rec. They then draw a line according to the number MPC has given. Anyone above that line gets SFT, below and they don't.
For cadets going up for the board you will see 2 different stats regarding cgpas. Tech majors typically need a 3.0/3,1 cgpa, while non-tech majors need a 3.3/3.4 cgpa.
The same happens for the rated boards, anyone above X and asked for pilot as their number 1 will get pilot, below it goes to their number 2 option. Caveat, that is the simplistic explanation, because as always the AF needs come 1st. If they are having too many placing CSO as number 2, and RPA as number 3, they may jump over the CSO desire to fill the RPAs.
Many colleges will promote the amount of slots they have had in the past. However, as Reaper said choose for the college as much as the det. The question you really should be asking these dets., IMPO are not their numbers or stats, but what is their breakdown.
For example: When DS met as a HS freshmen the CoC he asked what is the cgpa needed to get SFT at his det. What scores would be needed for pilot. The answer was 95% of the cadets that were non-tech with a 3.3 got both. 4 yrs later he commissioned as an O1 with a 3.4 cgpa and a pilot slot.
Now, had he gone to a different college the cgpa may have been lower, because let's be honest. Harvard, Yale, Princeton, etc. are high caliber colleges and the board will take that into consideration when comparing that cadet to University of Timbucktoo.
Additionally, colleges like ERAU will say they have the highest amount of ROTC cadets that get pilot slots, only after the AFA. This may be true, but it is also a very large det. Thus, you need to see what the cgpa breakdown is at ERAU in particular. You need to see what their attrition rate is for 100/200s because that number needs to be placed into the equation too, IMPO, just as important as the stat that gets SFT and pilot.
~~~ Every kid that is on this site in HS IMPO has the intention to commission. However, if you look at the attrition rates, @50-75% will leave AFROTC.
That is something you have to look at, and it is something you can only do if you visit or talk to the dets. Numbers don't lie, but you have to understand why those numbers exist. It could be ROTC was not they thought it would be or it could be the college was harder than they expected.
Choose the colleges you want to attend, and than make an appointment to visit the det., ask to meet with the CoC. Also ask to meet some 300/400 cadets. Every det is like a college, it has its' own personality. Thus, that will also be a factor when it comes to why the stats shouldn't matter as much. If you don't gel with the cadets, than you will not be happy, and you may leave or do poorly at school. With that train of thought...if you left because you didn't gel with the cadets or the college, you would pull down their numbers. It is just as much about your desires as it is about the dets ability, however, someone only looking at the stats would see the det. as being inferior to another det. You maybe throwing away a college because you only looked at the empirical values, without looking at your emotional values too.
The truly hard part for many is to find a det they like as much as the college, or college they like as much as the det. It is a balance that needs to occur to be successful in ROTC, but especially if you want a pilot slot from AFROTC.
