An audit of private colleges in Malaysia has unearthed serious quality issues, with only one in three colleges evaluated doing well in a quality assurance process that could be used by the government to approve or deny them licenses to recruit international students.
A burning question for developing countries is whether low quality private higher education is better than none at all, in circumstances where public systems cannot meet soaring student demand. Brazil decided it was and set about rapidly expanding its higher education system, including by opening it to private institutions.

For-profit colleges and universities represent the fastest-growing but also most controversial sector of private higher education in the United States.

The emergence and growth of private higher education in Poland has been widely regarded as one of the greatest achievements of the country's transformation in the 1990s. Now, however, the sector is endangered - not only due to great demographic pressure, but also to unfair treatment of private institutions by the state.
Critics of private post-secondary education often argue that foreign universities in developing nations are commercial and profit-hungry. But these debates ring hollow in Sub-Saharan Africa, where the majority of private providers are religiously-oriented with non-profit business models. Religious institutions are the fastest growing type of post-secondary institution in almost every nation north of South Africa and south of the Sahara.
Despite the efforts of some of the world's largest foreign private universities to set up shop in Australia, none have yet succeeded in making a profit from selling higher education - or even attracting significant numbers of students.
