Orgs represent the organizational structure of your school district. In general, this file will have one row to represent the district and one row to represent each building. The buildings will generally reference the district’s sourcedId in the “parentSourcedId” column.
For the identifier column, use the NCES ID for the school district. Go to https://nces.ed.gov/ccd/schoolsearch/
Note: sourcedIds for orgs should be unique across the entire data set.
