Companies that employ graduates to write essays and complete assignments for undergraduates claim they are not undermining academic standards because cheating occurs only if the students pass off the work as their own, something they discourage. In the other hand, reduced contact hours between undergraduates and lecturers make it harder for staff to detect work that is out of line with the student's abilities or writing style.

More and more students are plagiarising material - and buying essays online. According to one of several companies that trade in "off-the-peg" and custom-written academic work, they sell between 500 and 1,000 essays a week, mainly to overseas students studying in the UK. Prices start at £50.

A study conducted by students at Chulalongkorn University shows that large numbers of students are climbing the academic ladder not by hard work and smarts, but by cheating. Assignments were sold at a rate of 15 to 30 baht per page, depending on the subject matter and the urgency. Students could purchase multiples choice in advance or written exams.
