Blossom allows you to select which frameworks are visible on the platform. Go to More > Settings > Learning Settings > Curriculums to change your settings.
To switch a framework on or off, use the toggle. You can also set one curriculum as a default framework for the platform. To do this, click on the 3 dots, followed by ‘Make Default’.
If I turn a framework off, will I lose the past observation data?
No, you will not lose this data, but it will be hidden. If you need to view this historical data simply reactivate the curriculum.
