Again, the regulations are pretty clear about eligibility. Problem is many cadre @ campus never received briefings or a real class about what the regs actually say. Hell, when I was in ROTC my PMS and APMS didn't know that SMP cadets are not authorized to go to CTLT!
Point is - if you look at page 94 of AT 601-210 under SMP eligibility criteria, you must have at least finished MSII with the intent to become an MSIII, or already have enrolled. So, if you're technically doing it right, you can be an MS II early in your spring semester and if you've already signed up for the fall semester MS301 class, you are eligible.
Now - I know people have gotten away with becoming SMP before that time, but be careful. Although it's easy to assign soldiers to the SMP slot through ARLAS system for S1, HRC will do their due diligence. A friend of mine did get his pay docked later retroactively because he received E-5 SMP pay before he was eligible to become an SMP cadet.
Ultimately, you can always be a cadet AND and in ROTC, but there is a specific timeline for the SMP contract that promotes you to E-5 pay & the cadet position in NG/USAR. It's meant to reflect a cadet's status as a leader both as an MSIII in their ROTC detachment and the parallel experience of being a "third lieutenant" at their TPU unit. You're not supposed to receive SMP benefits as an MSI/MSII because you aren't ready (in the Army's eyes) and haven't been put in that leadership role yet.
