Will students who have not mastered kindergarten skills benefit from another year of kindergarten before going into grade one? It has been suggested that there is no other topic in education that has such a wide difference of opinion as those researchers who do not advocate retention and those who are convinced that a child should be given another year to grow and mature. This paper reviews some literature illustrating divergent views regarding kindergarten retention. Studies suggest that there is no reliable proof that grade retention is beneficial. Some researchers have concluded that allowing a child to repeat kindergarten provides a stronger foundation for essential skills needed for future grades, while others argue that retention has many negative consequences. Researchers cite studies which support their own particular point of view. This topic continues to be an important topic of discussion for educators and policymakers. With so many disagreements among researchers, educators can agree that kindergarten is crucial to the development of a child's education and that is essential to carefully consider the decision to retain or to promote children in kindergarten.
