After logging into Mosaic, press a Serving Period, but do not press OK.
Press the MODES button on top of screen.(If you do not see a Modes button, you have gone too far).
On the drop down list, press on Training Mode to open the training mode session.
After activating Training Mode, you may now work with any feature of Mosaic without impacting the actual district data! Feel free to experiment and work with the system as much as you would like! Once a student is selected while in Training Mode, the banner will no longer display. If you want to confirm you are in training mode before entering a transaction, simply exit the student transaction, and the Training Mode banner will be displayed at the top of the transaction ready screen.
