For example, the research has shown that ECE participation can lead to improved academic achievement, decreased grade retention, increased rates of high school graduation, higher employment rates and earnings, and decreased involvement with the criminal justice system. Yet, while these benefits can be achieved through ECE programs, they are not always realized.
Researchers agree that the answer has to do with program quality .
The findings from these streams of research provide insight into the types of ECE programs and constellation of services that appear to be more effective. Curriculum Content Studies of ECE curriculum have found few consistent differences among the tested curricula on children' s performance. Researchers, thus, have concluded that a variety of curricula can be beneficial in preparing children for school. Still, some studies have shown that direct instruction curricula may yield fewer benefits than interactive and affective curricula, especially on the development of children's social skills and behaviors. Many studies have found a link between positive child outcomes and teacher characteristics and practices.
