GreatSchools licenses data about school assignments and district boundaries from Precisely (formerly known as Pitney Bowes). We receive a data feed of school boundary and assignment information from Precisely on a quarterly basis and use this to make updates to this information we display on GreatSchools. Because we do not own this data, we are unable to make any manual changes to it.
To report an error in school assignments/school boundaries, please fill out this form and we will share it with Precisely so they can investigate and correct any errors. While we will continue to do our very best to facilitate these changes for you, we ultimately do not own the dataset and cannot make any guarantees about progress or timing.
