One more point.... Many Certificate programs as I mentioned earlier are really mini-degree programs and require semi-rigid to rigid admission requirements. For example the Public Health Certificates at U of Minnesota all require applicants to submit transcripts, letters of recommendations,personal statements and in some cases GRE or GMAT scores. Also for Public Health most of the CEPH programs use the SOPHAS or SOPHAS Express common application web portals and charge any where from $50-$200 to apply so I wouldn't call any of these a "weekend easy certificate" program. So if you're earned a Certificate that's a true academic "Mini-degree" program then you have every right and privilege to be an alumnus of that school.
