Admin > Config > Checkpoints Lock
This application allows you to set a date when the option to input assessment for a particular checkpoint will cease. You will be able to select all the checkpoints in the markbook and view the Step entered but if the CP is locked, you will be unable to change any data.
To enter a date or change a date, select edit and input the date.
Please note - to set only one checkpoint as open, all others must have a lock date before the current checkpoint's lock date. When the current checkpoint reaches it's lock date, the next one to be opened should have it's lock date edited to a future date.
