The footer of the Gradebook shows four at-a-glance metrics that summarize the entire visible table:
10 Students • 72 Lessons • 0% Mastery Rate • 0 Need Support
These numbers update based on your current Course and Unit filters, so they always reflect what you're currently viewing.
Students Count
The number of students in the current view. This matches the student count in the left side of the header.
In most cases, this just equals your classroom roster. If you've used the search field to filter students, this count reflects the filtered view.
Lessons Count
The total number of lessons in the current view (across the selected Course and Unit filter).
All Units selected: Counts every lesson in the course (often 50–100+ for full-year courses)
Specific unit selected: Counts lessons just within that unit (often 5–15)
This is useful for setting expectations: "We have 72 lessons to get through this year" or "This module has 8 lessons."
Mastery Rate
The percentage of student-lesson combinations currently at the Mastery (green) status.
Calculation: (number of green cells) ÷ (number of total cells, excluding "Not Started") × 100
How to interpret:
80%+ — Most students are mastering most lessons. Strong outcomes.
50–79% — Healthy mid-semester range as students work through content.
20–49% — Many students are stuck in "In Progress" or "Needs Support." Investigate.
Below 20% — Either very early in the semester or significant struggle. Check Classroom Performance for context.
0% — Either no students have reached mastery yet, or the unit/course is brand new.
Early in a semester, Mastery Rate will naturally be low because students haven't completed enough lessons to reach mastery on most content. It's most meaningful 4+ weeks into a unit.
Need Support Count
The count of student-lesson combinations currently flagged as Needs Support (orange).
This is not the same as the "Students Need Support" count on the Classroom Performance tab. Here's the difference:
Gradebook "Need Support" = total orange cells across all visible students and lessons
Classroom Performance "Students Need Support" = count of individual students flagged as needing support overall
So one student could account for 5 different "Need Support" cells in the Gradebook (5 lessons they're struggling with), but they'd still count as just 1 student on the Classroom Performance banner.
How to use the Need Support count:
0 — No orange cells in the current view. Either the class is doing great, or no students have hit the threshold yet.
Low single digits — Normal. A few students struggling with a few lessons.
Double digits — Concerning. Filter by lesson to see if it's concentrated in one place (then re-teach that lesson) or spread across many (then intervene with individual students).
Using Footer Metrics for Reporting
The footer is great for end-of-unit or end-of-semester reporting:
End-of-unit summary: "We covered 8 lessons in Unit 3. The class achieved a 75% mastery rate, with 3 student-lesson combinations still needing support."
End-of-semester summary: "Across the full course (72 lessons, 10 students), we achieved an 82% mastery rate."
These numbers translate well to administrator reports, parent newsletters, and your own end-of-year reflection.
