Learning Heroes believes that parents and guardians are key to improving schools for all students, especially those who have traditionally been underserved. The public education system currently does not have a systematic way to engage parents and guardians in understanding and acting upon information about their children’s academic and developmental progress. Research on large-scale systems change suggests that creating new sources of information that contribute to a system’s goals is one of the most powerful levers to shift a system’s purpose and values. This research synthesis from Learning Heroes and Populace highlights how parent actions can catalyze the system to be more responsive in meeting the needs of their own children and, ultimately, all students in a way that aligns with their definition of success.
