The main screen within the Tests module shows a list of tests that exist in your workspace (Admin user) or tests you have access to (non-Admin user). An example of this is shown below; there are two existing tests with their created/modified dates shown within the Created an Modified columns.
Tests are managed by tagging, in the same way that items, assets, and sessions are tagged. You define a hierarchy for how you want to tag tests, using the Tags module, and then assign the tests. For example, you might tag all tests by Subject and School Year so that they are easy to find. To find the tests, use the Search or Filters functionality on the left.
To open a test and view/edit the items, simply click on the test name within the Test ID column.
Note the ellipsis (...) within the Actions column on the right. This allows you to edit a test (same as clicking on the test name), duplicate or delete the test. You can also select a test/tests by using the check boxes; buttons appear allowing you to duplicate or delete the test.
IMPORTANT: You can't delete a test that has been used for examinees!
