To create a "District" School in Aeries for Infants and Toddlers or a "pending" school for assessments, populate the School Code (LOC.SC) with a number that is the combined (concatenated) number of the district's County Code (LOC.CC) number + the District Code (LOC.DC) number (42+12345 = 4212345).

For additional information, see Does a District need to obtain SSIDs for Pre-Kindergarten Students (Infants, Toddlers, Preschoolers) or Private School Students who are pending a Special Education assessment?
