It's constantly changing since Captain Stosz took over and since they sent a couple company commanders down to Parris Island. The class curriculum is changing, the knowledge is changing, SOP changing a little. One major change they have started to implement is the "Guardian Challenge" on Monday of week 08. It's based off of the Marines' Crucible except not nearly as intense, but it has gotten tougher from what I've heard. Basically you get woken up at 0300, have 10 minutes to get into ODUs, seabags with your rucksack in them, and PFDs, then you grab life rafts and start the hike around base. Then you head to the beach for 3 hours (probably 4 or 5 now, or they do more intense training). On the beach you put into practice most of what you've learned over the weeks. In addition, it's a mini endurance test to see if you can keep working through the conditions that they put you in. Luckily you're not in boots so it makes it a little more tolerable.
Some classes are being removed from what I understand, not sure if they are adding any new ones or not. Physical fitness requirements are still the same. You get your company colours in week 02 or 03, this also comes from the Marines. It gives you a stronger sense of teamwork and pride in your company, especially if the colours get wrapped up. We didn't blouse our trousers or iron our ODUs until week 04, nor did we start addressing personnel by their rank until the same time. Again, from the Marines the purpose being to teach you how to be a recruit rather than worrying about how your uniform looks.
Those are the big ones, but like I said it's constantly changing.
