Teachers not required to have licensure is not at all unique to BASIS. Guess what - the same pretty much applies to ALL of the charters and ALL of the private schools in DC - basically half of the schooling in DC is done in schools that don't require licensure. And ironically, guess who is getting the better results and who is graduating a higher percentage and who is putting more of their graduates into college and good jobs? It's the charters and privates.
Clearly, you don't know much about the school system here. Charters are not getting "better results" (what does this even mean?) and there is no longitudinal data that supports that charters are producing graduates who attend colleges or find 'good jobs' in greater percentages than DCPS students. Charters simply have not been around long enough to make this claim. Privates have been around long enough, but to lump private data in with charter school data (or lack of it) shows a shocking ignorance of charters, privates, and DCPS. Remember, BASIS is a PUBLIC charter school, not a private, and will have to serve the students of DC. The fact that its initial demographics fail to represent the city has more to do with it being an unknown, unproven school with a carefully strategic marketing plan than anything else. It hasn't opened yet. They may be promising a lot, and firing up boosters here (or at least one booster who responds to every thread with the if-you-don't-like-it-go-away ostrich stance at any hint that BASIS isn't already the best!thing!ever!) but all that means NOTHING. The school needs to open and we will all see if they can fulfill their mission.
As for hiring unlicensed teachers with little to no teaching experience or mismatched subject matter experience, yes, it's true that charters and privates are both allowed to do this, and BASIS can. Of course, whether or not they should participate in such bad practice is the question. Considering the task they have set for themselves, one would think they would seek out professional educators to help them meet their goals.
