Gifted ed is not one-size-fits-all, and cluster grouping among gifted students helps accurately assess the readiness, ability, needs, and performance/achievement of each student thereby helping students to be with their LOG in each subject (among the HG+, still all are not globally gifted, some may have asynchronous development or be in a plateau phase... they are still cheetahs).

Some have found it much easier to form effective cluster groups when the whole pool of students is gifted, and the range of abilities is not as wide as typically found in a general ed classroom.
