<p>The Juilliard pieces for a 7th grade-age kid are much more advanced than the ones you list:
- A three-part invention by Bach (or another work containing a fugue) or 2 or 3 contrasting movements from a suite.

Also, an hour practicing should be more of a minimum. And he should start doing theory if he hasn’t begun already – along the lines of Certificate of Merit programs, which have annual theory tests, performance evaluations, and recitals. If this sounds like a lot, don’t worry: he has many years to go before he would be applying to conservatories!</p>
