States that do not require an ABA accredited law degree to sit for the Bar exam?

Nashville School of Law allows students to sit for the Bar exam and practice in TN; however it is not (and has never applied to be) ABA accredited. There are many practicing attorneys in TN who have graduated from this school. My question is what other States if any could a Nashville School of Law grad potentially practice in? My friend whose stepmother teaches at the school told me that there are a handful of states that a non-ABA law school grad can practice in after so many years of practicing law in their home State... Is this true? Anyone know which States those are?

Thanks for any information.
