Tom, we'd like to provide an answer, but first need more information. What type of ranking are you looking for, i.e. state with top test scores? (In which subjects?) State with the most high school graduates? State with the highest percentage of students attending college, post-graduate? State with highest number of teacher OR lowest teacher-pupil ratios? As you can see, there are countless ways to measure "educational ranking" — let us know what you're looking for!
