The Gradebook should update as students complete lessons. If it doesn't seem to be updating, here's how to investigate.
Issue: Student Completed a Lesson, But Gradebook Still Shows Not Started
Step 1: Refresh your view Hard refresh the Gradebook page (Ctrl+F5 or Cmd+Shift+R). Sometimes the page caches old data.
Step 2: Check that they completed the assessment A lesson can be partially viewed without being completed. For the Gradebook to register completion, students typically need to finish the embedded assessment, not just scroll through content. Have the student confirm they answered the assessment questions and submitted.
Step 3: Wait a few minutes Data sync between student activity and the Gradebook is usually near-real-time, but can take 1–5 minutes during high-traffic periods.
Step 4: Verify the right lesson Make sure you're looking at the lesson the student actually completed, not a different one with a similar name. Use the Search students field and the Unit dropdown to pinpoint exactly what you're looking for.
Issue: Student Took an Assessment But the Grade Shows 0%
Step 1: Confirm they submitted Sometimes students answer all questions but don't click the final Submit button. Without submission, the assessment doesn't grade.
Step 2: Check for retake attempts If the student took the assessment multiple times, the Gradebook may show the most recent attempt — which could be lower than their best.
Step 3: Verify the right student Make sure you're looking at the correct student's row in the Gradebook.
Issue: Some Lessons Show Percentages, Others Show Dashes
Dashes ("—") in the Gradebook typically mean:
The student hasn't attempted the lesson yet
The lesson type doesn't have an auto-graded assessment (some lessons are content-only)
The lesson is locked behind prerequisite content the student hasn't completed
If you expect a percentage and see a dash, drill into that student's Student Performance view to confirm what they actually did.
Issue: A Specific Lesson's Grades Are Inconsistent
If one lesson shows weirdly high or low grades across many students:
The lesson assessment may have an issue (rare, but possible). Contact support if you suspect this.
Students may be sharing answers or the assessment may have a guessable pattern. Consider re-teaching or supplementing.
The lesson may genuinely be much harder or easier than others. Compare with the Improvement by Module chart.
Issue: Grades Look Right for Some Students, Wrong for Others
If your view of student grades doesn't match what students claim to have earned:
Pick one specific student.
Open their Student Performance view → Coursework.
Compare what you see there with what's in the Gradebook.
If they match: the student may be misremembering or mistaken.
If they don't match: there may be a sync issue. Contact support with the specific student and lesson.
Issue: Late Work Isn't Showing Up
When a student completes an assignment after the due date:
Their work still counts and is recorded in the Gradebook
The assignment shows as "Complete" status in the Assignments tab
The student's mastery on the lesson updates as normal
If a student completed late work and you don't see it:
Confirm they actually completed it (have them show you on their device)
Refresh the Gradebook
Check the right Unit filter
When to Contact Support
Reach out if:
Data discrepancies persist after refreshing and waiting
Multiple students show missing grades for the same lesson
A student's progress appears to have disappeared entirely
You can clearly identify a sync issue and need it resolved
Include in your support message:
Student name (or test student you've reproduced with)
Lesson name and course
What you expected to see vs. what you see
Screenshot if possible
