Unless the assessment instructions say otherwise, you can take a break during the assessment.
Taking a break in between assessments
After you complete and certify an assessment, you'll be taken to your assessment activities page.
Recommendation: When possible, take breaks at this point between assessments, rather than during an individual assessment. Your completed assessment(s) will be saved, and you will continue from this page when you restart the session.
Taking a break during an assessment
Unless otherwise noted in the instructions, you can pause an assessment and finish it later before the completion deadline by completely closing your browser. Your completed responses will be saved, and you will continue from where you left off with the same time remaining.
Important: Make sure to read the assessment instructions before starting to ensure you can pause. If you close your browser on an assessment that can't be paused or don't close your browser completely, the assessment clock will keep running and you might run out of time, which will record your score.
