Colleges may soon have a new reason — an antitrust lawsuit — to think twice about their relationship with the Common Application.

CollegeNET, which provides a variety of admissions-related services to college, some in direct competition with the Common Application, sued Common App last week in federal court, charging antitrust violations. And while the suit is only against Common App, it states that some of the 500 colleges that are members have been “co-conspirators” in some of the alleged violations.

When CollegeNET issued a news release last week about having sued Common Application, some admissions leaders were scratching their heads about how a service to process applications could violate antitrust law. The press release provided few details.
