<p>nick,
My son doubled in Music Composition and Music Ed. at Peabody, which needed an extra semester to allow for student teaching. Of course, he might have been able to squeeze everything into 4 years if he didn't have multiple minors and then decide to also go for a Masters at the same time. In any case, there are plenty of schools that allow a double in performance/comp. and education, and you shouldn't have too much trouble finding the right one for you.</p>
