Hi,
There are indeed schools that do not require an BA/BS. None come to mind in the US but some of the best schools in North America do not require the BA/BS.
Western Ontario:
"Special Admissions
Applicants that do not have an undergraduate degree are welcome to apply if they meet the following requirements:
Three university courses with at least a 'B' average
Minimum of seven years work experience
Three reference letters
GMAT
TOEFL (If applicable)"
York:
"Each year the School will consider applications from a small number of mature students who do not possess an undergraduate degree. To be considered, an applicant in this group must have at least eight years of high quality management experience and must have demonstrated a strong upward progression in his or her career. Additional information regarding the non-baccalaureate category may be obtained by writing or calling the Division of Student Services and International Relations (416) 736-5060 and requesting an appointment with the Admissions Officer."
Some schools have the power to grant degree waivers in exceptional circumstances. It is important to recognize that these waivers are the exception and not the rule.
