I have an article being published in another school's specialty journal. Its a rough process. I sent it out to about 60 journals. Most didn't even bother to reply. Only 3 of the 10 or so replies I got said they were going to consider it. One finally picked it up very late in the game. (I imagine someone withdrew or something, but whatever, I'm getting published!)
Its a hard process, and you need a thick skin, but its possible to do. I would recommend that you use ExpressO to find out the names of the different specialty journals at each school. Also try some 3rd and 4th teir school's main journal. You can then just look them up online and check out their submission guidelines. They will generally tell you there if they accept student pieces. If you want, you can use ExpressO to actually submit your article. However, if you're sending it to a lot of journals, this can be expensive. And you could also waste money by sending it to journals that don't take student pieces.
Do submit it to any specialty journal that falls within the range of your article though. Most won't look at it, but you may get lucky.
