The Gurian Institute (www.gurianinstitute.com) was the first organization to nationally codify boy-friendly success strategies into professional development programs, then teach them to educators, parents, and community members in school and community pilots around the world. From their efforts over the last two decades, success data has developed using test scores, grades, and discipline referrals as statistical markers.
This process began in Kansas City, Missouri, in 1996 and included a two-year pilot in six school districts; it then expanded into every state and numerous other countries. To learn more about the success data, you can read Boys and Girls Learn Differently and Saving Our Sons, as well as visit www.gurianinstitute.com/success.
Other organizations have also been generating data to show the efficacy of boy-friendly strategies.
