Hi @mscottmcauliffe , If you haven't found the script yet, its available on PowerSource under the Trillium Core 4.13.10 update page.
We have prepared a script package to assist Boards in performing a mass override of SHSM awards. The script shsm_mass_update.zip will create a new table to hold two pieces of information for a student who has been identified as requiring an SHSM override: Student OEN and the BSID of the school granting the SHSM (and diploma). Please note: Students that will have their SHSM overwritten should have the Award OSSD separately flag set on. You also must complete your achievement cycle prior to running this script.
Please read the readme.txt file within the zip file for instructions.
