Well, summoning magic is a bit more advanced than traditional magic; maybe I put it a bit far out of reach for first years... But, always open to ideas; perhaps the Major to get to the 'Evoker' class faster, probably more along the lines of 'Tamer' or something, though 'taming' creatures is more of a physical aspect rather than signing them to a contract as an evoker; I may add it into the 'Major' section in the character profiles. As for the contracts themselves, always something to have up in the air; some creatures might be more interested in the naughty aspects, others would prefer contests of skill or strength.
Summoning students directly would be something else entirely... I may limit it strictly for Erdgeists that can be summoned, since they aren't in traditional bodies, unlike the other species. Seeing how they aren't bound to any magic contract like some creatures might be, actually summoning a student would require a long process to do, which the result may be them finding a unique Evoker's contract scroll... which will be no easy task.
And if you're going with a Fox for your beastkin choice, I can see them being rather sly as well as a bit of a jokester... So evasive with magic talents to them, but physically frail if cornered.
One thing I now forgot is a 'starting equipment' section for the Student character sheet... Though shouldn't be hard to implement.
