Yes! Classwork.com is compatible with Respondus's Lockdown Browser and other anti-cheat technology as long as students can retrieve data from the URLs listed in this article: What URLs should my school allow list to use Classwork.com?

Lockdown Browser keeps students from opening other windows, or using disallowed apps such as calculators while completing a Classwork assignment. You may want to use that for assessments.

Classwork does not have any browser locking or tab locking capability built into it. If you feel this is an important feature, let us know at support@classwork.com. We'd love to hear from you!
