Apollo's creed could be that we all deserve the chance to advance. The for-profit Apollo Education Group provides educational programs through a number of subsidiaries, including online stalwart University of Phoenix. The largest private university in the US, the University of Phoenix accounts for about 80% of Apollo's sales and has an enrollment of more than 900,000 students in degree programs ranging from associate's to doctoral. Other schools include Western International University (graduate and undergraduate courses), South Africa's MBA-grantor Milpark Education, and UK-based BPP Holdings, a provider of legal and financial professional training. Apollo went private in a $1.1 billion transaction in early 2017.
