Every district sends records to TEA differently. Students move to out of state districts and cannot be tracked. Students leave school and enter the workforce. Students from Mexico. There is a need for more accurate reporting.
Kids move away from the district.
This is not the school's fault, but the records still count against the school district. Small districts' turnaround on requests is slow because one person wears many hats within the district. Districts are financially accountable for things they have no control over like pregnancy, dropout, drugs, etc. This is not fair. Hard to get or report accurate data, particularly in high transient districts - i.e., border districts.
