With the new Promotion system, do Skillport hours still count as promotion points? DL hours show on my ATRRS transcript, but not ERB?

If the hours are on your ATRRS transcript then they should also go onto your ERB. Get with your S1 and show them your ATRRS hours to get it fixed. I would also go to the HRC website and check what courses are worth points, they have a list on the Enlisted Promotions page.

Check with your S1 or HRC website.

You will have to check to make sure the courses count toward correspondence. But yeah they do count still. Might take a few days to show up on ERB. A lot of courses don't count towards correspondence hours though.
