I would think a piano teacher would be great, assuming your child learns piano like they learn other academic things. I would probably go first to our piano teacher if I had to find a recommendation for my son. We are homeschooling now after 2 years in PS. I could have never found anyone in our school environment to give this kind of recommendation.
Just for the record, we have not applied to DYS. I'm just too cheap to go for full testing without good reason. Maybe someday we'll do the testing for other reasons and then we might. DS's end of year standardized testing was well in range.
