The CA Dept of Education used to require GATE programs. In 2014, they made them optional, so schools stopped offering them. What's shocking to me is that this happened even in districts where there are lots of high-performing kids, with families that care about advanced learning. When we moved to Menlo Park, we were surprised that our highly-rated school doesn't have any programs for kids who are advanced in learning. They just talk about how all their lessons have a "low floor and high ceiling" which sounds nice in theory but doesn't work very well in practice (at least when you have a mix of kids who range from 1-2 grades below grade level to 2-3 grades above grade level).
