The practice where advanced learners are separated from regular learners is referred to as Tracking.
Tracking is classifying students by scholastic expertise into associations for all subjects or specific courses and curriculum inside a school. It may be attributed to as streaming or phasing in several schools. In other schools, tracking is a meritocracy that relies on teacher instructions, patterns, and student urge to determine deployment. Some tracking systems applied to as ability-grouping methods which allow students to different categories based on their recognized ability in that subject.
