Overview
Purdue University ranks a lofty 2 out of 257 schools in the 2026 College Free Speech Rankings with a score of 76, a C speech climate grade. Purdue earns a “green light” Spotlight rating and has adopted both the Chicago Statement and institutional neutrality. Disappointingly, Purdue recently invoked its institutional neutrality commitment in deciding to stop circulating an independent student newspaper on campus and demanded that the paper remove “Purdue” from its web address. This overzealous application, which occurred after data was collected for this year’s rankings, may cause Purdue’s rank to go down next year.Student perceptions place Purdue in the top 25 for “Political Tolerance,” suggesting broad willingness to host speakers from across the ideological spectrum compared to other schools.
Purdue can build on its strong policy foundation by tightening protest guidelines to discourage shout-downs and educating students on when expression crosses into unprotected conduct.
Highlights

I could not express who I would vote for because they were saying bad things about that candidate.
When submitting assignments that reflect political opinions, I fear that if I write something that goes against my professors beliefs they will grade me based on that.
