I am not sure exactly how leadership grades work, but i do know it is very important for your SPC to know you. Like I said before, at OCS, we were told to fly under the radar. At TBS, you definitely want your SPC to know you...in a good way. I had the unfortunate experience of going through something pretty bad at TBS, and unfortunately the staff knew a bunch of ins and outs of my life. But out of anyone in my platoon, I probably knew my SPC better than anyone, and he probably knew me better than the rest of the people in my platoon. I just wish it could have been better,
Before I continue, I just want you to know, that sometimes, you have to take care of yourself first, and if anyone treats you poorly, please put yourself first. I made the grave mistake of letting someone in my personal life affect my performance at TBS, must to the disappointment and exasperation of those around me. Please feel free to contact me if there is something horrible going on in your life. Sometimes all a Marine needs is for someone to listen. You can find my contact information on the last page.
You'll have three command evaluations (maybe four?) during your time at TBS. The later ones count for more of your grade than the initial one, so don't fret if you don't get off to a good start. Obviously first impression are important, but don't let a first impression define you.
You're billets will matter, you're personality will matter. Be positive, be optimistic, be trustworthy. The last is most important. Be someone who someone else would trust with their life. Your future Marines need a good leader.
A passing evaluation is a 75%. However, these evaluations are compared to your peers. Don't throw your peers under the bus, but be the best person you can. You'll be surprised how much compassion is important. The evaluations are done Fitness Report Style, and are in unobserved time. I'm still getting the hang of Fitness Reports, but the prior service Marines in your platoon will be a great resource in how these work.
