Here are a few things that you can do to lower tuition costs: Good grades (2.5 GPA minimum) in high school will equate to KEES scholarship money for Kentucky residents. The higher the GPA the higher the amount of the scholarship (see link). Apply for any other scholarship money that your kid may be eligible to receive from the university, your employer, charitable organizations, etc.
Next, you could send your kids to community college for the first two years at a fraction of the cost ($147/credit hour vs. +$360 at UK) of a four year university and they could live at home. Then transfer to a state school for the last two years where all of those community college credits would be accepted toward their degree.
ROTC is an option if your child would be willing to serve time in the military. They would get a virtually free education and a guaranteed job upon graduation.
A part time job is also an option. Universities often have part time job opportunities. Working 15-20 hours a week is totally doable while going to school full time (undergraduate).
Make sure that your kid is working toward a degree that will lead to a job. Otherwise, why bother with the expense. Going into a trade out of high school makes more sense that getting a worthless degree.
