This year is running a little bit differently than last year in that if a four degree is not on the path to be recognized, it is up to that individual and their leadership to get them up to speed. If the four degree is still considered to be deficient when the time comes, they will not participate in recognition, and there will be no make up recognition. But like zachtx already said, these four degrees should already be aware of their deficiencies, and each of these cadets is capable of bouncing back and being ready to rock when 10 March comes.
Ultimately, it comes down to putting in the work. If a four degree is borderline, there are improvements that need to be made to their attitude, aptitude, etc. In the end, there should not be a significant number of four degrees who are at risk for this. Their supervisors should be doing everything they can to help these 19ers get on track, but it is also important to note that they themselves need to want it as well. This is a much better system in that it gives leadership the opportunity to really develop their followers, and offers the 4 degree in question a chance to grow and develop.
With all of this in mind, I doubt that your cadet is at risk for not being recognized. He or she may be stressed about all of the training sessions and requirements leading up to it, but is absolutely able to meet the standard. Best of luck and I hope this was helpful in some way!
