Unfortunately, the push for changing the gifted programming and services at your school to emulate SFUSD math detracking may be rooted in a desire to achieve equal outcomes for all pupils... which is often accomplished by capping the growth of students at the top.

Gifted programming & services designed to meet the varied academic needs of pupils will follow a philosophy of matching the program to the child, rather than matching the child to the program. Practicality necessitates grouping students. Rather than batching students by chronological age, cluster grouping by readiness and ability is an approach backed by research, including:
