University Degree Program (UDP) is or was an unaccredited consortium of diploma mills run by Americans Jason and Caroline Abraham (of Brooklyn, New York; also known by their Hebrew names Yaakov and Chaya Rochel) beginning in the 1990s. In 2004, The Chronicle of Higher Education called UDP the "granddaddy" of diploma mill operations.
The Chronicle of Higher Education reported that the University Degree Program recruited "students" over the telephone from call centers in Romania (where the call center also sold fake international driver's licenses) and Israel. Telephone salespeople, who were paid on commission and received performance-based bonuses, could offer degrees in any field requested. The Abrahams created websites for a diverse variety of bogus institutions whose names were printed on diplomas. Customers were not told which of these "universities" would issue their degree. According to the Chronicle, UDP sent a letter to customers stating: "The policy of not disclosing the name of the University protects you against unscrupulous individuals who do not approve of self study and life style improvement." The letter also said that this was done to avoid "bad publicity".
The operation was estimated to have sold more than 30,000 "degrees" and received proceeds totaling $50 million to $100 million or more.
Two victims of the UDP fraud interviewed on BBC News reported that between 1996 and 2002 institutions of the non-accredited University Degree Program claimed to be subsidiaries of reputable universities such as the Glasgow Caledonian University or the City University of London and ran an actual distant-learning program online or by mail. The correspondence addresses of the bogus institutions were in the immediate vicinity of these universities in order to create a genuine background along with the websites. Study material was prepared in accordance with the syllabus on the website and was regularly sent to the students, who previously had agreed to pay a yearly tuition fee. According to BBC News significant efforts were made to let these institutions blend into the genuine universities with distant-learning programs. These efforts also included personal contact between student and teacher by email or phone. In late 2002 the Abrahams commercialized the operation and began to merely sell their bogus diplomas by using agents.
