rcm (from 2015)
The exam syllabus of Canada's, Royal Conservatory of Music is huge. Rather than change every few years, this one lasts for a decade or so, and even then many of the pieces will remain the same. This gives teachers plenty of variety; no need to keep teaching the same few pieces, nor do they need to keep buying new exam books! So the RCM provides a fantastic resource for anyone, teacher or student looking for graded piano music. There are 10 levels, plus 2 preliminary levels and a diploma at the top. Broadly speaking the levels follow those in the UK, though perhaps +1/2, so ABRSM G2 = RCM Level 3.
If the music is in the public domain, I've given easy access to the sheet music which, in most cases, I will have found on www.imslp.org.
So here are some of the pieces. I hope you find what you're looking for, but if not and you're a subscriber, you may like to commission one?
