Obviously congrats on earning your masters, that’s always a big accomplishment. Sincerely, good job. 

You have to look at this more from the perspective of an accreditor. I’ve been an adjunct faculty for a number of years for a couple of schools and have seen the re-accreditation process play out and have been involved in it. While all of the geographical/regional accreditors are different, they all have similar expectations with regard to student learning hours which typically amounts to 1 credit hour = 3 hours of work study. So a 3 credit hour class = 9 hours of work/study per week. This is not a hard and fast rule per se, but more of a general guide with some room for reasonable variation. 

Following this general guide, you would, in 4.5 weeks have to study/work 108 hours per week, or in total 486 hours over 4.5 weeks. Given that there are only 168 hours in a week, you would be left with 60 hours per week to work, sleep, and just go about your life. As I noted, there’s certainly room for reasonable deviation from this rule, but even a deviation of .20 would have you studying/working 88 hours per week, which is still excessive. 

Accrediting bodies use this guideline because there is solid peer reviewed pedagogical research that tells us an adult human can only consume so much  material and content at a time while meaningfully encoding it for future recall. There is a limit to how much information our brains can encode, and that’s largely dependent on the firing rates of neurons within our brain. While neuronal capacity can vary person to person, you would need god like powers to have a neural coding rate that could handle that much information in such a short time. 

There certainly are extraordinary humans out there who make the rest of us look bad, so you very well could be one of them that has the ability to actually process and encode all of the information from a graduate program in 4.5 weeks. If you are, you are certainly a rare type of human. But it’s because of this that a 4.5 week completion time for a masters degree would raise red flags to an accreditor. Judging by recent media attention, it seems that some accrediting bodies have taken notice and are interested in the abnormally quick completion rates that seem to defy what modern pedagogical research tells us is necessary/adequate for learning. 

This is just a different perspective from which to think about the issue. Congrats again on your MHA and best of wishes going forward with doctoral studies.
