Kathy, that's so awesome that the company will help out.
That was the first thing I did when I was thinking about taking this position in the company five years ago, was ask if the boss's boss would approve reimbursing an MLS degree. The company only reimburses $5000/year (when I started back in 1992, they were providing full reimbursement for both bachelors and graduate degrees; now, they only fully cover bachelors), and I'm factoring in annual increases in tuition and fees, so that $2000 is only an estimate. (I'm also thinking about using some of the 2007 reimbursement check to pay off my high-interest-rate credit card, and then pay off that part of the loan over the three years I'm in the program.)
If there's a discrepancy in your favour between what you pay and what the full time students pay, some universities will charge you a make up fee that you have to pay in order to graduate. I had to pay an extra $2300, which nobody told me about until after I had started my program and the university kind of buried it in their regulations. (It wasn't on the Grad Faculty, Financial Services websites or in the Student Handbook, I had to go digging in the regs of the university.) So make sure to ask up front about that.
That really sucks! No, the LEEP (online) program is charged at the same rate as the on-campus one; the only difference is that LEEP's rate is factored as a four-credit rate, not per credit. We don't get the various on-campus student perks (insurance, etc.), but then, we don't have to pay for those perks, either.
And listen to me putting myself in with the LEEP students when I haven't even been accepted yet! Jeez, talk about making assumptions...
