@puffin, you said it well! Truthful, succinct, eloquent. I think we both wish that we had cheerier facts to share. Unfortunately this is not a good time for the gifted.

BINGO!

Common core standards ushered in a slew of measurements and data collection to enforce uniformity and compliance with teaching to the standard. The current educational theory is equal outcomes for all pupils. Teachers and schools are rated/ranked according to closing gaps... achievement gaps, excellence gaps.

It can be difficult to advocate successfully when the schools' rating/ranking and the teacher's job may be on the line... making them rather disinterested in meeting the academic & intellectual needs of gifted pupils.
