The way our school did math until a year ago was: accelerated students like my son took Algebra I in 7th grade, Geometry in 8th grade, Algebra II in 9th grade, Pre-calc in 10th grade, AB AP Calc in 11th grade, and BC Calc in 12th grade.
Now it's CC 2/3 in 7th grade, Integrated 1 in 8th grade, Integrated 2 in 9th grade, Integrated 3/pre-calc in 10th grade, etc.
If my son skips Integrated 1 next year, he could take 3 years of AP math at his school or dual enroll at our local state university.
