I think "recruit" is more suited to the army than university and I would never use the word in this type of context

I assume this is a recommendation letter for a student to gain a place on a university program(me)? (UK or US?)

These types of letters usually point out a student's abilities and how they will not only benefit from the course/program(me) but will actually be an asset to the school. A sample letter below. Look at the final paragraph

"and therefore is an excellent candidate for your school. I highly recommend that you consider her application, as she will be a great asset to your program. I’m sure you will find her to be a student whose talents will only shine further through your graduate program..."
