This error occurs because a student received English Learner Services (LAC record) who was reported as English or Sign Language.
Do not address ANY CERT errors until after the enrollment updates (SENR, SINF, SELA and SPRG) files have been posted with few to no errors. Most CERT errors are caused by file extracts that have not yet been posted error-free or from data that has not been correctly populated in Aeries.
The data entry on the student's Home Language (STU.LF) needs to be verified and updated using the Home Language Survey. If the student has a Language Assessment record (LAC), verify and update the data on the record with the correct information.
