I think that the DADA course next year should include a patronus quiz... its just an idea i had.
Patronuses aren't taught in the third year yet. On EU, the patronus lesson only seems to be in the seventh year. Just look at the description: "It is an immensely complicated and extremely difficult spell that evokes a partially-tangible positive energy force known as a Patronus," I don't think third years can cast this yet.
Also, some people may want to choose their own patronus. Tests aren't always accurate and they may get a result they're very unhappy with.
i think that is more up to the teacher but what eve said. further more i think that it would be more of guidelines then actual rules. like you get a link to an offsite test in the lesson
