How do I prove to my new unit that they should send me to WLC?

You have just graduated from the PNC. That right there shows you have not yet proven that you can even do your job yet, let alone show that you can be a leader. Best way to show you are ready: Go to your first assignment, be a hard worker and team player, attend whatever leadership courses that are available.

You will have to show leadership potential and wait your turn. Put your time in at the unit showing them you are ready. You can't just show up as a SPC with a nice paper record and expect to be sent. You have to prove yourself above the others who are also trying to get a slot. I wouldn't expect to be sent for at least a year if you are JUST coming out of AIT and that's a best case time line.

complete SSD's and score 300 on apft ?

First things first adjust to being in the army now that you will be. Complete SSD1 before you even bring it up. Be 15 minutes ealry to everything. Give up some of your weekends and be part of battalion or company held events. Thats part of leadership and moral support for your unit that your peers never over look.

Increase your PT score push to run A train if you do not already.

And yes ask to compete in soldier of the month after a solid 2 months of performing in the top of your unit. Stay positive and motivate other.

Do not behave like a PFC behave like a SGT look at SGT and take notes and perform.

Stay hungry and go after your goal.

Hey its no longer WLC its BLC.

Show initiatives that prove you're are ready to become a leader.

Lol, you'll get there, just chill out. Show up, shut up, do your job. Ask people about themselves rather than reveal information about yourself and your accomplishments. No one wants to hear about you, they would rather talk about themselves. This will help you appear likeable. If you haven't, read the book, "How to Win Friends, and Influence People," by Andrew Carnegie. It was recommended to me as a private, and now I'm suggesting the same for you.

Performance and experience. Go above and beyond when given the opportunity.

Brown nose your leaders. Be loud all the time and get a 300 pt score.

You need a better PT score to start off and also your just getting into big army you should stay off the radar do the right be at the right place right time and right uniform and don't cause any trouble for about a year or until leadership picks you

As a NCO you need to train soldiers, your guidance and mentorship is important. You will know you are ready by proving to your leadership that you can follow three basic steps.

1. Know your job and your leaders job.
2. Know why your your NCO asks you to do something.
3. Know what needs to be done and do it before it is even asked of you.

If you follow those steps consistently you will be ready for the next rank. And sent to BLC before you even realize you accomplished all three steps.
