The attention that the Coach pays to the Cadets is directly proportional to their Access Grade.
A slightly unfair approach that makes more sense on closer inspection; The Access Grade is not just a simple number to divide People into different classes, since their current status, as Cadets or Recruits, is also taken into consideration.
However, knowing that someone has Access Grande 3, even if they are just a Cadet and possess a Category 2 Singularity; Is no different than saying that the individual in question is endorsed globally as a competent fighter, of course, the Work and their IGNUS are important too.
Which is why someone with more or less overall prowess can be rated higher or lower, as the Battle Capacity or the Category of a Singularity are part of the entire evaluation, not the only factors.
