Right, and all the programs I referred to are also guaranteed promotion after Basic as well. But you'll still be an E-1 in Basic and so if you are looking at some outstanding scores on something posted for E-1s in Basic, well, it's possible those E-1s are people who enlisted with a guarantee of higher grade on successful completion of Basic, not starting at the bottom except insofar as everyone enlisting starts at the bottom in Basic.
Apparently the navy considers scouting to be roughly equivalent to an AA.
"Scouting
Provide evidence of successful completion of Eagle Scout or the Girl Scout Gold Award requirements and you are entitled to be enlisted in pay-grade E-3."
