How does the Navy decide if you qualify? Is it based on trapping all 4 landings on the 3 wire? Or is it a cumulative score of all your landings? Or is it something else?
There are several parts to it. Every pass has a grade, from Wave Off-Pattern, No Grade, Fair, OK, and
OK, with a few other small options, all assigned a score of 0 to 4. You need a GPA of at least 2.5 for your passes at the boat. You need 10 traps in your period, and a 60% boarding rate (Trap to Bolter ratio). HOWEVER, you can be waived to qual if you have less than the necessary GPA or boarding rate if paddles thinks you're on an improving trend. HOWEVER, with a passing GPA and boarding rate, you can fail if paddles thinks you're on a decreasing trend.
The one thing that is set in stone is a single cut pass is an immediate failure.
