2. There's zero shortage of teachers in music ed. Any of UNT, UH, or UT, - alone - graduates more teachers than retire statewide on an annual basis. Multiply that by all three together, and add in every other school that has a teacher prep program, from Tarleton to UTEP to A&M Kingsville, and there's a huge glut. Plus there's dozens of people that come from out of state too.
3. No. Politicians will just continue to blame "lazy teachers" and then lower the bar. Florida already allows "military spouses" to enter teaching with nothing more than a few hours of classroom observation. Precisely what qualifications does marrying a soldier grant you to teach algebra?
4. It's been a crisis for a decade. That crisis has been ignored because it doesn't suit the narrative, and it was mostly being felt in urban and rural schools. Now that it's affecting suburbia, people are paying attention.
5 and 6. Disrespect. From parents, from students, and from administrators. And from school boards in their pay scales that don't keep up with inflation.
