Children who had a high quality preschool experience were more likely to graduate from high school then children from the same neighborhood who had no preschool experience high/scope

Yes, for an example, I went to a private preschool & now I go to a charter school, i learned most the material a while back & it’s easier to understand. As you progress through the years of school, it gets harder & the children who didn’t go to the preschool may not understand the material as well as (I) did, so they may feel like it’s hopeless for them and just drop out and or fail.
