Many of them don’t want to try to meet the standards. They have been given free education, told that all their ills are due to white-on-minority racism, and generally discouraged from holding themselves accountable for their failures.
In the grownup world where teachers are held accountable for student success, where lack of academic progress from the students means lack of financial progress for the teacher, many find it easier to just go into some low level government job that hires based on affirmative action. They are offended that victimhood doesn’t get them all the way to the rainbow’s end.
In many districts teachers that don’t meet “standards” get kept often. Administrators get kept often not meeting “standards”. “Standards” get lowered and changed to protect administrators. Teachers shaken out are usually ones that don’t get along with or cover for the administrator. They could get targeted by insecure teachers too. Believe one reading your explanation may underestimate the mess that is there. Some districts are hiring anyone they can get for a reason. More veteran teachers command a higher salary and there is incentive to shake them out on the part of the administration. The teachers going out only being the teachers who aren’t good teachers is a myth.
We believed that too until my wife began doing work at our children's schools while living in Louisiana.
What we learned was that teacher workdays are not times in which they can do useful things like catching up on grading and improving lesson plans. Instead, they have to attend various training seminars for which they receive no continuing education credits.
Ditto for scheduled early release days when kids are let out at lunchtime. Teachers have to stay at school as if it was a regular day attending training seminars for which they receive no continuing education credits.
Superficially, teachers do receive generous holidays but what isn't realized is unless they use their annual vacation time during Christmas and Spring Break, they will have to report to school during those times, or take unpaid leave.
Teachers that actually try to teach and interact with students can't sit at their desks and grade papers during class. This then means grading has to be done during planning period, or after hours. Because of school crowding, the teacher may not be able to stay in their room during planning period because the class will be used by another teacher. If the school is short substitutes on a particular day, a teacher may lose their planning period and be required to cover a class as a substitute.
Periodically, teachers will be required to attend meetings with the parents and case managers of any children they have receiving special education. These meetings may take place during the teacher's planning period, or after hours.
All of this causes teachers to do grading and planning during unpaid after hours time.
Because of teacher turnover, remaining teachers may find themselves being rescheduled by principles to teach unfamiliar courses which places additional burdens of planning and preparation on them which must be done after hours.
Then there is parent communication which must be done after hours mindful that every word typed in an email could come back at them in a lawsuit.
Depending on the school, administrators may expect teachers to be seen periodically attending after school events and activities for which they do not receive compensation.
Depending on the school, administrators may also expect more senior teachers to take on "leadership: roles by "volunteering" after hours time as advisers to student groups, or by joining faculty school improvement teams.
Teachers are required to attend open house nights but are not compensated for it.
When you add up all of the work a teacher must do throughout the year for which they are uncompensated, that time then seriously erodes their summer vacation time.
