1 month after my first daughter started state college last year, they announced a new grant program, offering 4 years of paid tuition for incoming freshmen and transfer students, beginning the following year. Qualified applicants needed to meet family maximum income requirements, which we do as a FIRE family. The program apparently used no taxpayer dollars.
In order to qualify, my daughter would have had to transfer schools mid-semester and take a minimum amount of credits second semester to remain a freshman. Another problem: due to her taking AP classes all through high school, she was considered a sophomore after the first semester, so she would have had to withdraw out of just enough classes to remain a freshman, but not too many to qualify for a transfer to another school. All this would lead to a 1 year delay in her degree, probably costing more in lost income than the tuition savings.
On top of all that, we have been contributing $3,000 per year to her 529 plan that has grown to enough funds for 4 years of state tuition, room and board, so she doesn't need the free tuition anyway.
