I am a laywer who doesn't much like being a lawyer - just so you know where I am coming from.
First, it is NOT at all necessary to do pre-law in college in order to go to law school. As a matter of fact MOST students in law school did not do pre-law. I would recommend using college as a time to check out a wide variety of classes and see if something else is interesting. Even if she is 100% sure about law - a degree in political science, philosophy, government, etc would be a better preparation than a pre-law degree. If she is interested in science the field of intellectual property is very hot for people with tech or science backgrounds.
Another great idea would be to try and get her an intership in a law office. The day to day life of a lawyer is NOTHING like what you see on TV - better she learn that before spending money on law school!
If she is interested in social justice work (a great and noble field) she needs to understand the economics of that. Those types of law jobs pay very poorly. If you get out of college and law school with sizable school debts to pay off - you will not be able to afford to go into social justice type work for many, many years. This is a trap a lot of law students have fallen into.
All that being said - there are a few pointers that can help. First, make sure that you limit debt as much as possible. Go to a state college, live at home, etc, etc. I was very lucky in having high SAT scores and LSAT scores. I then picked a (private) college and a (private) law school whose average SAT/LSAT scores were below my scores. Schools are always looking to move up their averages and they do that by attracting bright students. I had excellent scholarships to college and to law schools (and still managed to get quite a lot of debt!)
Finally, there are law schools that specialize in social justice/environmental law. These schools may offer programs to help pay off loans after law school for those students who enter into low paying fields. I attended an excellent small law school that happens to be the number one environmental law school in the country. They do work hard to help their students afford to go into those types of jobs.
Good luck to you and your daughter!
