Conservative think tanks have pumped out interesting policy research arguing that requiring grad degrees to teach 1st grade math doesnt actually improve the quality of teaching, but weeds out a lot of passionate people who dont want to jump through hoops/load up on debt/waste time in a classrooom.
In my opinion any policy that encourages more people interested/passionate in teaching to get into it is a step in the right direction. The schools dont need to hire these people if they arent up to snuff.
I work as a software engineer, taught adults coding for a few months, found it extremely rewarding and hope to teach as my second career when i get sick of staring at computer screens all day. Very bizarre to think that a PHD in computer science might be required to get a grad teaching degree before being allowed to teach high school kids comp sci in many districts/states in my area.
Military spouses also make sacrifices for the country i have no issues allowing them to not have to sit in a classroom for two years as well, obv some might have not have the appropriate appliable skills though and i would hope they wouldnt end up getting hired.
