I have a diploma in CS, but not a bachelors degree, but 10+ years of practical engineering experience. I'd love to work towards a masters in CS, but most online schools don't accept my diploma and work experience as equivalent. I attempted to apply for a GT online masters and was soundly rejected without consideration. There are always ways around, and candidates that should be considered based on potential. But some kind of a qualifier, even a certificate, that would allow candidates like myself that would love to be engaged through some kind of qualifier or conditional acceptance would allow more people to get engaged and show their ability and commitment to being successful.
