I bet on this happening at some point with the introduction of the Net Price Calculator requirement on college websites. College Abacus has launched their Kayak.com-like service for price shopping colleges. I was certainly not the only person to perdict this.
Right now they say they have over 2,000 schools available to search but it is not clear if the colleges agreed to be a part or if the service is simply scraping results from their sites (just like kayak.com has done in the past and run into issues with the airlines, see here and here).
If College Abacus is not asking permission of the colleges, what might the reaction be? Should be interesting to watch, especially that they try to tackle some of the more complex (some have over 50 questions) Net Price Calculators.
