SB 765 - This act requires the Department of Elementary and Secondary Education to annually calculate a transient student ratio for each public school building and each school district. The transient student ratio must be published on the Department's website and in the school accountability report card for each district and public school building. The Department must also publish on its website an aggregate transient student ratio for the state. The transient student ratio will use data, including the number of students enrolled in the district or school, the number of students who withdraw from the district or school, and the number of students who are enrolled, withdrew, and later reentered the district or school. Each school district must report annually to the Department any information and data necessary for the Department to calculate transient student ratios. This act establishes how the student assessment scores and other performance data for students who have not been enrolled in a district-operated school for the previous full school term will be used when calculating the district's performance for purposes of the Missouri School Improvement Program. The scores of any student who has not been enrolled in a district-operated school for the preceding school term will not be used. The scores of any student who has been enrolled in a district-operated school for the preceding school term but not for the full two preceding school terms will be weighted at thirty percent of the weight assigned to a student who has been enrolled for the full three preceding school terms. The scores of any student who has been enrolled in a district-operated school for two full preceding school terms but not for the full three preceding school terms will be weighted at seventy percent of the weight assigned to a student who has been enrolled for the full three preceding school terms. This act is similar to provisions contained in CCS/HCS/SCS/SBs 493, 485, 495, 516, 534, 545, 595, 616 & 624 (2014). MICHAEL RUFF
