I attached a screenshot below of what it looks like. At my school we had to take them at certain times, but I don’t remember when our subscription opened. I want to say that the tab didn’t show up until we were allowed to take the assessment, in order to keep people from taking them early; We take one in March and one in June to assess our progress towards board-readiness and for class stats. However I didn’t even look for the assessments tab until March when we did our first assessment, so I can’t say for certain that it was missing until then. If your school told you the assessments were included as part of your assessment, I would maybe contact them about it if you still can’t find the tab. You may only be able to access it after the assigned time if they use them as progress assessments.
