How the platform works
Grading and tracking
Which criteria are assessed, how the grade for a Speaking activity is built, which grade appears in Grades when there are several attempts, and how the platform identifies students who need attention.
Speaking criteria
A Speaking practice is graded on five criteria, each from 0 to 100.
| Criterion | How it is obtained |
|---|---|
| Pronunciation | Measured on the student’s audio. |
| Fluency | Measured on the student’s audio. |
| Grammar | Assessed by AI on what the student said, based on the activity’s level. |
| Vocabulary | Assessed by AI on what the student said, based on the activity’s level. |
| Cohesion | Assessed by AI on what the student said, based on the activity’s level. |
Grammar, vocabulary and cohesion are judged against the activity’s level, not against a native speaker. Comprehension is a Reading criterion, not a Speaking one.
Overall score
The overall score is the activity’s grade. In the practice report it is called “Overall Performance”, and in the details of a grade in Grades, “Overall Score”. Since October 16, 2026, for a Speaking activity it is built by section:
| Section | Weight | What it is worth |
|---|---|---|
| Words | 25% | The average pronunciation and fluency of the best recording of each word, multiplied by the share of the list practiced. |
| Phrases | 25% | The same, with the phrases. |
| Interactive conversation | 50% | The average of the five criteria across all of the student’s evaluated turns, in their finished conversations. |
- A section that the activity has and the student didn’t practice is worth 0.
- If the activity has no words or no phrases, its weight is split among the other sections.
- A criterion with no data is left out of its section’s average.
- The grade combines all of the student’s attempts at the activity and is rounded with halves rounded up.
Until October 15, 2026, the overall score was the simple average of the five criteria. Grades calculated before that date keep that rule until they are recalculated: see Grades calculated before October 16, 2026. The step-by-step calculation, with examples, is in Practice report metrics.
Grading is automatic. The teacher views the grade along with the per-criterion details and the feedback; they don’t edit it by hand.
Which grade appears in Grades
| Case | What is shown |
|---|---|
| A Speaking activity with several attempts | Since October 16, 2026, the activity’s grade with all of its attempts. It is recalculated when another attempt is graded, as long as the assignment allows attempts. |
| A Reading activity with several attempts | The grade of the practice with which the student completed the assignment. Repeating it afterward doesn’t replace it. |
| A course | The average of the lessons already graded. The missing ones don’t count as zero. |
| The student’s average | The average of everything assigned to them. Whatever they haven’t done counts as zero. |
In Speaking, another attempt doesn’t by itself recalculate the grade in the cell in two cases: if the assignment has a due date, doesn’t allow late submissions and the student practiced that attempt after the due date; and if the assignment is archived or deleted, or was canceled for that student. That grade can still change for other reasons, which are explained in Practice report metrics.
Since October 16, 2026, the details that open when you click a grade also show each section’s weight and the value it contributes to the grade, the practice time, and whether the activity counts as finished. See Practice report metrics.
The colors in Grades are fixed: 75 or above is high, 45 to 74 is medium and below 45 is low.
Minimum grade
There is no configurable minimum passing grade: the grade has no bearing on whether an activity counts as finished. It counts when the student finishes the practice, with two conditions if the assignment has them: that they finish it before the due date, unless late submissions are allowed, and that they reach the minimum practice time. See Activity status. For words and phrases, 70 or above marks the item as achieved.
Export
A class’s grades are downloaded in Excel (.xlsx) from the Grades view. Since October 16, 2026, each grade is exported as a whole number, rounded the same way as on screen: 64, not 64.38%. An activity without a grade is exported as 0.
Student tracking
Who needs a nudge
The shortcut is on the “Your groups” page. It lists a student when, in any class, one of these two conditions is met:
- they haven’t completed any of that teacher’s assignments;
- their score is more than 8 points below that class’s average.
It doesn’t take into account days without signing in or past due dates, and it only considers assignments created by that teacher.
Students to review
Within each class, the summary shows who hasn’t started and who is below the group, using the same 8-point cutoff.
