This page shows that as of yesterday (Jan 15, 3013) the The Achievement Program will be known as "The Royal Conservatory Music Achievement Program". So maybe an update on the website will be forthcoming...eventually deleting "Carnegie Hall" from the title.
Actually, "The Royal Conservatory Music Development Program." There is a link now to a press release
describing what's going on a little bit more: Carnegie Hall is stepping out of being involved in this program to focus on other "national and international music programs", and RCM will solely handle registrations and records for TAP... I mean, TRCMDP.
An interesting nugget in the press release is that there are 4000 teachers registered with this program (what shall
we call it for short? just RCM now?) in the US, and 6000 assessments were taken last year. I wonder what the distributions of assessed students/per teacher is. I would have expected a higher ratio. I wonder if teachers tend to expect to send most of their students to these exams, or if they're only sending certain (highly motivated? high achieving?) students, or if a lot of teachers are registered but haven't yet sent students or worked this program into their studio.
By comparison, in Canada there are 100,000 assessments per year.
