Supplemental and concentration grant amounts are calculated based on the percentage of “unduplicated pupils” enrolled in the LEA on Census Day (first Wednesday in October) as certified for Fall 1. The percentage is based on data from the current year and two prior years, and equals: Unduplicated count of pupils who are (1) English learners, (2) meet income or categorical eligibility requirements for free or reduced-price meals under the National School Lunch Program (NSLP), or (3) foster youth. “Unduplicated count” means that each pupil is counted only once even if the pupil meets more than one of these criteria See Education Code sections 2574(b)(2) (schools operated by county superintendent) and 42238.02(b)(1) (school districts and charter schools). Divided by total enrollment in the LEA See Education Code sections 2574(b)(1) (schools operated by county superintendent) and 42238.02(b)(5) (school districts and charter schools). Supplemental and concentration grant funding is based on district-level data. Therefore, intradistrict transfers should not have an effect on LCFF funding. With respect to interdistrict transfers, the unduplicated data is reflected in the district in which the students were enrolled on Census Day. If a student transfers after this day, they will not impact the Unduplicated Pupil Percentage (UPP) of the receiving district; their counts will remain in the original district. However, because average daily attendance (ADA) is a factor in how much supplemental and concentration grant funding an LEA receives, the transferring students will generate supplemental and concentration funding for the receiving district, but it will be based on the district’s UPP for the students enrolled as of Census Day.
