If a person is not capable of or for other reasons cannot attend an ABA approved law school, it's time to consider anther career. The study of law is not for everyone. The legal market is saturated as it is, and many students attending ABA approved law schools have difficulty landing any job, let alone one that they want. Even if you "have a job lined up" before you even enter law school, attending a non-ABA school is a bad idea. For one, your area of interest in law will likely change after you enter law school, and the lined up job may no longer be appealing. Also, the name on your degree will follow you for the rest of your life and will hinder you later in your career. The law profession can be very elitist, with great emphasis being placed on the school attended.
The general rule is to get into the best law school you can get into, with a few exceptions . The better ranked the school, the more opportunities await you fresh out of law school and down the road. If the best law school you can attend happens to not be accredited, pursue other options.
