Is Combat Water Survival Training a graduation requirement for ROTC/commissioning?

I just got told recently by my cadre that passing the CWST is no longer a requirement for the mission set '18. However, you should have the capability to pass it. They change the commissioning requirements every year. I was in the same boat as you and took swimming classes. My school lets you do the CWST events you can. So I have been diving off the board and treading water, I just couldn't pass the rifle swim. Also a tip for the water tread part, the only requirement is to just keep your face above the water. So if you cannot tread you can technically float on your back. Good luck!

I couldn’t swim to save my life before ROTC. I took swimming lessons last semester and past CWST with ease.

I contacted Cadet Command about this a year ago. I was told that CWST is a comissioning requirement if your PMS says it is, it's program specific. Your PMS can grant a waiver if you are unable to pass. At my program, the PMS declared CWST to be a requirement, therefore he would not grant waivers.
