Two thoughts on this...

1) I hope the dedicated AP English teacher is not disciplined (or dismissed) for teaching at an academically advanced level.

2) Regarding the quote: "the principal, aggravated and arrogant, told me schools no longer believe in academic excellence because demanding subjects no longer appeal to the mainstream student or to his parents"... unfortunately many on these forums have experiences which may indicate that some schools may work to make demanding subjects unappealing to students and parents... as the schools work toward equal outcomes for all... essentially mainstreaming all students... cutting down tall poppies.
