Well, it seems to be a tinkering rather than a major overhaul. They're including helpful things like sample viva voce questions and answers. They're making a few changes to recital lengths and repertoire for performance diplomas, and making the recital and viva more independent, so candidates will be able to retake one section without the other. There aren't any details of the changes yet, just an indication of the areas they will be in.
The main changes seem to be in substitutions: no substitutions for DipABRSM and LRSM programme notes, and CT ABRSM is no longer accepted as a substitution for LRSM Teaching, although it will continue to be a substitution for parts of DipABRSM.
Issues such as child protection, equal opportunities and maintaining a safe learning environment may be tested in the viva for Teaching and Directing diplomas.
There are other changes, but this is a quick resume of the ones which caught my eye. There are references to the diploma section of the website - it might be worth checking there.
I now have to decide whether to go ahead with my (still vague) plan of taking LRSM Performance in December, or whether to wait for the new syllabus in case it's more appealing
