Linkins et al. believe that the prescriptive approach to character education is limited by the use of a small range of character strengths that are to be realized within a narrowly defined understanding of character. In comparison, they argue that character education that reflects the Peterson and Seligman classification is broader in scope and leads to many positive outcomes for students. The benefits include enhanced life satisfaction, student engagement, and academic achievement. White and Water's state that it is premature to generalize the results of a small number of studies regarding the benefits of strengths-based programs. Caution is required before generalizing the results of these studies given they were conducted within specific school settings, at only a few year levels and only tested in schools that are in Western countries. Mandela shows us how leadership can cascade through a country, organization, community, or school.
