Pre university musicianship books

[quantum]

Has anyone used any musicianship texts designed for pre-university students?  Introductory musicianship, or material that prepares the student for university entrance or a diploma such as ARCT.

I'm not sure what specific skills you are looking to teach.

I've used these books myself and with students:

Also https://www.sueanderson.co.uk/ - gave this to a fellow teacher recently who found it very useful.

They might be a bit basic for your needs. Can you be any more specific?

I guess my original post was a bit vague.  The students would be taking private instrument lessons (many of them in the RCM system).  A majority of them would be piano, but also some violin and guitar.  I am designing a course that would improve their musicianship skills and would compliment their private instrument study.
