There are public school districts in California which couldn't be more eager for specs to push standards forward by another 0.5+ years because the Common Core is still catching up from behind to their de facto standards, but there's a seriously powerful (perhaps majority) democratic and political will to hold standards back.
What the Common Core and Equitable Math should not be understood as is as a new way of teaching or learning math. Neither of these are revolutionary. All parties involved understand that there's an existing supply of math teachers across the nation who are comfortable teaching some curriculum at some level, and that a true re-arrangement or re-imagination of subjects carries high institutional friction.
In other words, we might rearrange Geometry to be taken before Algebra, but replacing Geometry with Linear Algebra (per Gilbert Strang's suggestion) would be revolutionary.
Common Core demolished the education system in this state, along with the other acts to “improve” education. The optional AP was just a single African American studies class.
Education in public schools is just straight terrible here - teachers live like 2 hours away and hate their lives, topics are low difficulty and uninteresting, and the entire system predicates itself on the SAT, which you need a part-time tutor to cover your ass for, unless you want to spend every weekend doing a test; most can’t afford that.
