You hired someone with a strong corps background for your summer staff. Their credentials are real. Their technique is sound. Three days into band camp, your students are frustrated, your staff member is visibly recalibrating, and you're not sure whose fault it is.

Nobody's, really. And that's the problem.
The Credential Is Legitimate. The Mismatch Is Still Real.
Corps experience means something. The instruction is intensive, the standards are high, and a staff member who spent several years inside that system usually knows what good looks like. There's no argument there.
But drum corps is a curated environment. The students who show up to that first rehearsal already self-selected — they auditioned, they got cut once and came back, they learned to absorb correction fast because the alternative was going home. By the time a corps instructor starts teaching fundamentals, they're working with students who already know how to be taught that way.
Your students don't have that background. That's not a criticism of your program — it's a description of the population. A high school section has freshmen who have never marched, juniors who learned a different technique from a previous staff, seniors who have some ingrained habits that will take real time to shift. The range in one rehearsal block is enormous compared to what a corps tech is used to managing.
When a staff member has only ever taught the narrow end of that range, they don't have a mental model for the wide end. They know what the endpoint looks like. They're less sure how to sequence the path from zero to there — because in their experience, students arrived closer to the middle already.
What It Looks Like on the High School Practice Field
The instruction doesn't fail dramatically. It usually fails quietly. The tech gives a correction that would land immediately with a corps-level student. Your student nods but doesn't actually integrate it, because three prerequisite skills that the correction assumes they already have — they don't. The tech gives the correction again, a little sharper this time. The student tightens up. Progress stalls.
That's the mechanism. It's not that the instruction is wrong. It's that the correction is aimed at a student who isn't in the room.
A capable tech will figure this out. Most do, eventually. But "eventually" might be two weeks into a six-week summer, and you've already lost momentum in the section that needed to move fastest.
This compounds when the staff member is covering a caption they don't naturally connect with classroom teaching — visual, brass, percussion, it doesn't matter. If their instinct is to model and expect imitation, rather than to break a skill into components and sequence it, you'll see the same pattern across the board.
What to Actually Hire For
The question isn't whether someone has corps experience. The question is whether they have experience teaching students who don't.
In interviews, the line that tells you the most is how a candidate talks about a student who wasn't getting it. A tech who describes adjusting their approach - breaking the skill down differently, identifying which sub-skill was actually missing - is describing a teacher. A tech who describes giving the correction more times, louder, with more demonstration, is describing a performer who teaches. Both are useful. They are not the same.
For summer staff specifically, prioritize candidates who have taught in secondary school settings, who have run sectionals for programs with wide skill ranges, or who can talk concretely about how they sequence a skill from zero. Corps background can sit on top of that. It shouldn't replace it.
And when you're onboarding staff before camp, don't just walk them through your show - walk them through your students. Tell them where your weakest third is starting from. Give them realistic context about what "average" looks like in your program. A good tech will use that information. A great one will ask for it before you offer it.
The Organizational Problem Underneath This
Staff hiring tends to happen fast and late. A spot opens up in April. You know someone, or someone knows someone, and the credential checks out. You confirm availability, you lock it in, and you move on to the next thing on the list.
That's a reasonable process under time pressure. The problem is that it optimizes for availability and credential, and treats pedagogical fit as something that will sort itself out on the field. Sometimes it does. But when it doesn't, you're usually finding out during the three weeks you can least afford to absorb the information.
Staff fit is a show design problem. The instruction your students receive shapes what the design can ask of them, which shapes what the show can accomplish by October. It's all connected earlier than it feels like it is in April.
That's part of what I think about when I'm working with directors on custom show design at White Mage Music - not just what the score and the visual package will demand, but whether the program is set up to actually get there. If you're building something that needs to work for your students - not a hypothetical corps student, not last year's group - that conversation is worth having early.

The credential on the résumé tells you where someone learned to teach. It doesn't tell you who they learned to teach. Those are different questions, and only one of them matters for your camp.
