We're homeschooling and our oldest is 8, but I checked the website of the gifted middle school program and it seems students can go anywhere in the sequence
Math-6/Math-7/Pre-Algebra/Algebra-I/Geometry/Algebra-II/Advanced-Math, so it seems they are really trying to cater to the advanced kids. (For context, in this district, the majority of students are "below proficient".)
