The number of double or multiple degree programmes is growing and opinion is divided on whether they are beneficial or an example of academic fraud. A proper debate is needed on standards and quality so they do not become dismissed as "discount degrees".

Although Chinese students have been going to America to study for decades, their numbers have grown dramatically in the past few years. Many of them have only a basic knowledge of foreign universities and difficulty making sense of complicated applications. As a result, a huge industry of education agents has arisen in the country to help guide them — and, in some cases, to do whatever it takes to ensure that they are accepted.

Once comprehensively surveyed, the magnitude and reach of fraud is becoming clear. For example, research suggests that the majority of applications from a number of large student-sending countries are either significantly embellished or outright fraudulent. As a result, tens of thousands of international students, having passed through visa and admissions systems, are enrolled all over the world based on school transcripts, financial support statements, recommendation letters or test scores that are untrue.

According to the most recent report of Accredibase, the UK-based background screening company Verifile Limited, there was a staggering 48% increase in the number of known degree or diploma mills operating worldwide last year. It identified more than 2,500 bogus institutions across all regions, but primarily in North America and Europe.

Paper mills and cheat sites are losing ground to social and user-generated Web sites as sources of material for student papers, and Wikipedia rules above all others as a source for plagiarism. A third of matched content derives from online sites where people contribute and share content, while only 15 percent of content matches have ties to sites specifically promoting "academic dishonesty".

Turnitin News recently conducted a study that examined which Internet sites students used in their written work. They classified 110 million content matches in 40 million student papers that were submitted to Turnitin over a ten-month period.
