I don't think you can convince her. All you can do is make it clear that any debt is on her. Don't provide money or co-sign on loans. You can also get information on the average amount of debt graduates usually have. Finally, I would get job and graduate school placement rates for the school. I'll bet they're pretty dismal. In academia, this isn't even considered a 'real' institution of higher education (based on the curriculum and the educational rigor of the institution -- which may or may not be based on their religious foundation (I had to say that last even though it's more like a religious high school),

discuss student loans, the job placement prospects, and the national ranking of the school in that subject - ie probable value to cost ratios. pure economics.
Suggest she keep and open mind until you visit two or thee other viable options. For my daughter we visited five before we found the one where she felt it was a good fit to attend. My son visted all those and one of his choosing before deciding to stay here and go to a state university.
Also point out part of the college experience is the opportunity to be exposed to a great variety of people and beliefs. doesn't always happen but in theory...

If it isn't a full scholarship, I might just talk about economic practicality. ECD is awesome, but it isn't going to bring in lots and lots of extra cash as far as I know. Also, does she know about all their rules? Dress code, you need to submit an excuse within 48 hours if you miss church, no water balloons, no social dancing...Look over the handbook with her.

tell her to come to canada. she can get a better education for less that 10,000/yr.
and with the exchange rate you get a 30% discount.

No one truly chooses a college based on god calling them. There's another reason that the excuse is masking.

If I were her father, I would tell her that I want her to go to a non-sectarian liberal arts school because I feel that she would be better served by being exposed to a wide range of information and ideas.What religion, if any, she chooses is up to her, but I do not want her to mix education and religion. Also I would tell her that I will not support any or her costs at ORU, but will help all that I can in a liberal arts college choice.

Who is paying for it? Perhaps talk to her about how long it will take for her to pay back her student loans on the pay that she will be able to get with an early childhood development degree.

Looks like God needs to come up with 35k and then 41K for three more years. Bet the Masters program is even more!

Are you paying the tuition? If yes, you have a leg to stand on. If no, give it up. It is her decision, her money , her future.

Have you discussed where the rest of the tuition will come from?

Liberty University might be cheaper
