Teachers have the ability to set a Lockdown Browser mode for students while they take an assessment in Otus.
The option for the Lockdown Browser will appear in the final popup screen before assigning the assessment to a class. Be sure to turn this feature on by moving the toggle to the right as shown in the image below.
(Here is an article that will walk you through the process of Assigning an Assessment).
***Students must download the Lockdown browser to their computer the first time they take an assessment using this feature.
A popup will appear guiding students through the process after they click Take Assessment.
Once the Lockdown Browser is installed on a student's device, the student will select "Take Assessment" from the Assessment module.
