The best paying education affiliate programs are at http://www.search4clicks.com , http://www.collegeanduniversity.net and http://www.vantagemedia.com . Though http://www.affiliatefuel.com is strong for the online colleges.
In terms of what you get as an affiliate, not a lot to be honest. There’s virtually no creative (except at AffiliateFuel), just a bunch of lead forms for you to send your traffic to.
