Overall Rankings
The Overall Score combines seven unique dimensions to identify the top ranked college campuses for student free speech and open inquiry. The top-ranked colleges have the highest average score among all students surveyed and have the most open environments for free speech. Read more on how this ranking was calculated.
The Liberal to Conservative ratio (after the first school on the list, you'll need to click the down arrow at right of each listing to see added data) is particularly interesting.
This list is a load of shit and a political hit job. Hillsdale college and Pepperdine (where my daughter attended) are absolute leaders in free speech on campus.
Hillsdale is a beacon of education on libertarian ideas. Pepperdine is an evangelical religious-based university.
