Thank you!
I think my music teacher would accompany me (hopefully) she's grade 8 piano so it would be okay! how long do you think it would be a good idea to leave it before entering? Is it a really big step? I was going to do the 2009 xmas exam period - would that be too soon? I don't want to do it in the summer because of school exams and too much pressure...
Thanks

PS i don't really understand the programme notes part - do you just write about which pieces you chose?
Diplomas are really professional qualifications and require you to be well above grade 8 standard. A diploma accompanist would usually have a diploma in piano, or at least be at that level of playing, as the recital should sound professional.
If you have been to classical concerts and bought a programme there will have been programme notes in it. You do write about the pieces you are playing; if you look on the diploma bit of the ABRSM site they give you a lot of advice about writing the notes.
If you only scraped a pass at grade 8 I think you should leave a minimum of two years before your diploma. My son is doing his DipABRSM on clarinet in July after getting grade 8 merit in March 2006 and then grade 8 distinction with different pieces in March 2007 (he got 28, 28, 29 on his pieces) and his teacher is still not certain that he will pass the recital part of the diploma. The stamina required to give a 35 minute recital is much greater than needed for grade 8, and the standard expected for the pieces is much higher.
You will also have to be excellent at sightreading. The quick study is a piece of grade 6 standard which can be up to 5 minutes long; you get 5 minutes to look at it and are then expected to give a professional performance of it. The viva voce (an interview where you get asked a lot of questions not just about the pieces you have chosen and your programme notes, but about other composers writing at the time, and about your instrument generally) is also difficult to pass.
Bear in mind that AS levels are a lot of work, and see how you settle into Sixth Form before you commit to a diploma. Why not learn some new repertoire and do grade 8 again in a year's time with a view to trying a diploma the year after? If you can't get a distinction in grade 8 there really isn't any point taking a diploma yet.
