My D lightly used a coach and wasn’t advised to change materials depending on the program (besides basic audition requirements, of course).
I have heard 4 faculty members/program heads/adjudicators at 3 different programs talk about how they could tell when someone had been coached (in all cases, especially from one “national coach/place”), and it wasn’t complimentary. They used words such as “robotic,” “inauthentic,” and “over coached,” and there was eye rolling and exasperated sighing.(Two of these people had direct conversations with me about it; two were sitting right next to us at a breakfast at Unifieds, and we very clearly heard their entire conversation.) That said, every coaching person/company discussed on this forum has nice results for most people, and two of the three aforementioned programs take people who have been coached. I bet the third does, as well, but, since they were from an acting only program, I don’t know much about them. Part of it is that these people (2 of them, anyway; I don’t know about the 2 I overheard) are disgusted by the fact that coaches are needed, and they wish this process hadn’t ballooned like it has. But, that’s not necessarily the fault of the coaches; they are filling a need. To me, it’s like the debate about the chicken and egg. And, when these coaches do their jobs well, they help the students present their most authentic selves and target places that would most likely fit them.
But, yes, people will say to stay off CC or not get a coach or make sure your auditioner stays off the auditioners’ FB page… You know what? I absolutely needed CC, and I’m really glad D had a national coach. In fact, I wish we had hired her earlier. (We didn’t hire her until August/September of D’s senior year.)
And, yes, now the word is out to bring focus to one’s face by wearing solids and avoiding obvious patterns, make girls’ legs look long (thus the nude heels–although my D ended up going with either character shoes or blue shoes after not feeling as comfortable in the nude ones, which was supposedly a big no no), avoid jewelry or scarves that distract, etc., and so, of course, everyone now auditioning for MT tends to look the same! (It doesn’t seem to be the same for acting only auditioners.) I’ve read this advice from programs themselves and in coaching materials. Again, what came first: the chicken or the egg? In this case, it appears that some programs advised this, coaches learned it and advised it, and then it became universal to anyone who has any knowledge of this process. If the programs don’t like it, it seems they have the power to fix it. I bet they could effectively get the word out in one audition season. I’m not saying they would want to. The reasons for dressing like that are, IMO, valid; it does help bring focus on one’s face and own physical self. It is difficult to stand out among others with those strict parameters, though; my D searched for months before she found a dress she thought simultaneously satisfied those guidelines and showed her individual personality. (And, she’s a very picky shopper, which made the hunt take even longer, I’m sure.)
