Since you are saying Illinois Tuition waiver, I am assuming this is something your state does for the cadets, not something AFROTC has control over. They do not direct states to give tuition waivers. In other words is this an ANG issue that Illinois has in place?
Or are you speaking of the IS board for this yr? Last I heard was they were meeting at the end of 1st semester, or the beginning of spring. Remember, for the last 2 yrs, there have been no IS AFROTC 3 yr boards, so many are hoping there will be one this yr. There had been talk last spring that they would bring it back, but that was before AFA reduced their class size.
I am not sure there will be one this yr, due to the budget and the AFA. Historically many AFROTC cadets apply for AFA too, as your DS did, and AFROTC DOES NOT SPEAK to AFA when awarding scholarships. Many of these cadets accept the scholarship, knowing that they will not be penalized if they are appointed, but at least they had Plan B. LY in the early spring, after many of them had scholarships in hand were told the AFA was dropping appointments by @350. That means AFROTC now would actually have more taking them up on the offer and allowing them to get closer to their "number" without having to offer the IS option.
It is all about the numbers, both manpower and budget.
P.S. if he gets a 3 yr, realize to check that date on the DodMERB because if he had in July/Aug or even early Sept, it may fall out due to the 2 yr requirement before he contracts. If it does he would be forced to get a new one and no money will be paid, including scholarship and stipends until he has his medical in place. It has happened at our DS's school a couple of times, because that is the one thing they forget about when doing their paperwork. They may be cleared to go for the scholarship board, but not clear to go when it comes time to implement the scholarship.
