redshirting

Morley Safer reports on the rising trend of "redshirting," delaying kindergarten until children are 6 years old. Will this make these students more successful in school and life?

Academic redshirting: The practice of postponing an age-eligible child's kindergarten entry by a year, typically one whose birthday is very close to the cut-off date. Academic redshirting is often done in order to provide some extra time for social, intellectual or physical maturation.

In rare cases, a child may be academically redshirted in order to give him the advantage of an extra year's development when playing sports in high school.
