Is it usual for a grade 5 player to still be reading treble clef for trombone? I have absolutely no idea myself having never played brass instruments, thanks in advance for your thoughts
In the United State I, a jazz trombonist, read Bass Clef as well as the trombones in my Concert Band class. I'm going to assume that your in a british brass/marching band (I think they read treble clef) and while it isn't that odd, I would suggest they learn Tenor and Bass Clef if they are serious about playing trombone and continuing onto it in college.
The Trumpet, French Horn, and Baritone read treble clef, The tubas and Trombone usually read Bass and can go up to Tenor (and in the case of trombones, treble)
But this might just be The United States
