I just checked the Achievement 4 C/TSgt test, as can be found here: https://www.capmembers.com/media/cms/CAPT_782_Drill_Test_FINAL_746403DBED6F4.pdf
on page 9. (Not a secured item) and based off my going over the listed sequence in my head, the element(s) should start and end in line formation, not column formation, so the element leader should be on the formation's right, your left.
If the grader dinged you for "not keeping the element leaders in front of the formation" when the only marching commands are - using the tested Cadet facing the formation in line normally as a starting reference - a forward march when the formation is in line after an about face (they're marching away from you in line), a left flank (now they're marching forward in column), a right flank (now they're marching in line away from you again), and finally a to the rear (now they're marching towards you in line), then that is definitely a fault on the tester.
1.) The test setup specifically calls for a single element of 2 cadets at minimum. Not a flight.
2.) How is it possible to keep the element leader(s) in front of the formation at all times and still execute the listed sequence? Impossible, period. It sounds to me like someone is misreading something somewhere in a drill manual about keeping element leaders in the front and applying that instruction somewhere to a condition where common sense says no. "Oh, you're marching in line? Well of course the element leaders are not suddenly going to break ranks and trot out to in front of the line formation!"
3.) These are the graded items of the test:

5. Overall Leadership

I certainly don't see anything on that list about where the element leader(s) is/are, aside from maybe
the alignment item, but that's a big stretch.
Seriously, follow up - respectfully - with your Cadet chain of command, and possibly your Senior leadership too if needed, you got a bad deal.
