This classification permits expenditures to be segregated by instructional level. Many state departments of education differentiate elementary, secondary, and postsecondary costs so they can calculate interdistrict tuition rates, compute general state aid, or both.
The following definitions and correspond with levels of instruction used by the NCES Common Core of Data program. States and school districts should use the definitions that are used in their jurisdictions. Grade span can also be changed to age span when structuring a nongraded school or school district. Each classification is presented by a code number followed by a description.
