The main menu provides an overview of the modules available in Ada, which correspond to major portions of the test development cycle. Moreover, these modules correspond to security roles commonly used by assessment organizations; perhaps item writers only have access to the Items module, and a staff member in charge of student enrollment only has access to the Examinees module.
Note that the modules are also available in the side navigation on the left, so you can easily switch between modules at any time.
To start working, click on one of the cards or on a module in the side navigation. If this is your first time in the system, click on Items so you can start developing test questions.
