Missing assessment result dates can cause issues with API integrations and exports into systems outside of ScholarPack.
You can add missing statutory assessment result dates from Admin > Students > Bulk Assessment Result Dates.
Select the year and click Choose.
You'll then see any results missing a date.
Add the date in, then click Add Date.
You'll then be taken back to the Admin > Students > Bulk Assessment Result Dates page, with a note when the date was added successfully.
