What term refers to efforts aimed at improving schools?

The term that refers to efforts aimed at improving schools is "School Reform." This term encompasses various strategies and initiatives designed to make systemic changes within educational institutions to enhance their effectiveness, increase student achievement, and address inequalities. School reform can include changes in curriculum, teaching methods, governance, and policies, among other areas, with the ultimate goal of creating a better educational environment for all students.

In contrast, other options like "School Enhancement" may imply improvements or upgrades, but they do not specifically capture the broader, systemic nature of reform initiatives. "School Preservation" typically focuses on maintaining existing traditions or practices, rather than improving them. "School Innovation" can refer to creative or new approaches within the education system, but it does not necessarily imply a comprehensive strategy aimed at overall improvement, which is the essence of reform.
