This seems to be (mid-way) formal and in a very polite register. I don't know what version of Eng. this is intended for, but in UK we would tend to use this term, rather than the more personal form here. Although variations could be used.

I would use this fixed term because correctly written texts depend very much on common usage, and although this is not a literal translation, the idea of what one would "like to do" is still inherent in the term.

Could also use "prospective teachers"

If not teachers, then perhaps:

"prospective practicioners"
