When you lock an assessment it makes that assessment unavailable to teachers. When an assessment is released it becomes available to teachers. The default value for system and custom assessments is released.
To open your custom assessments mouse over the “Assessment Builder” icon and select “Custom Assessments.”
Click the “Actions” menu next to the assessment you would like to lock or release and click the appropriate action.
It will display “Locked” under status when an assessment is locked. It will not show anything under status if the assessment is released.
