The Open University
Affectionately known in the United Kingdom as the OU, the Open University is probably one of the largest distance learning universities in the world. Established in the late 1960’s our mission has always been focused on enabling those who would have otherwise not been able to access higher education.
At any moment, we have between 150,000 to 200,000 students studying with us on undergraduate, postgraduate and research degrees. There are many other accomplishments, but rather than reading our opinion of the OU, take a look at this WikiPedia page and form your own view.
