Extra artistic recommendations for BFA audition schools?

Good Afternoon All,
My son has booked his live auditions and submitted his apps for the Class of 2021. He is wondering if it would help in demonstrating interest to the schools to send them a few more recommendations from the acting/voice/dance teachers and directors with whom he’s worked. Do you think that would be beneficial, or is so much of the decision based on the audition that it’s not worth bothering the recommenders with such a task?
Thank you!

I think the decision comes from the room, not the recommendation

My experience has been that all that matters is the audition in the room and grades/scores for those school that care.

audition, audition, audition. No need for extra recs.
