Son programas especiales para estudiantes superdotados (pull-out programs), en los que se les imparte formación adicional.

"Gifted students are **pulled out of a heterogeneous classroom to spend a portion of their time in a gifted class. These programs vary widely, from carefully designed half-day academic programs to a single hour each week of educational challenges**. Generally, these programs are ineffective at promoting academic advancement unless the material covered contains extensions and enrichment to the core curriculum. The majority of pull-out programs include an assortment of critical thinking drills, creative exercises, and subjects typically not introduced in standard curricula. Much of the material introduced in Gifted pull-out programs deals with the study of Logic, and its application to fields ranging from Philosophy to Mathematics. Students are encouraged to apply these empirical reasoning skills to every aspect of their education both in and outside of class."

"A pull-out program is one in which gifted children are taken out of their regular classroom for one or more hours a week and provided with enrichment activities and instruction.

Pull-out programs may begin as early as first grade, but more typically start in third grade. They are usually content specific; that is, they they generally provide enrichment in language arts (particularly reading) or in math."
