Gradebook
The assessments (previously gradebook) aggregates scores from exercises, assignments, and other graded activities into a unified view of each learner's performance. It also controls certificate generation.
How the Assessments Work
The assessments are weighted scoring systems. You define:
Which activities contribute to the grade (exercises, assignments, attendance, etc.)
The weight of each activity (how much it counts toward the final grade)
The minimum certification score (the threshold for earning a certificate)
A minimum score per activity — Each activity in the gradebook can have its own Minimum score. Learners who score below that minimum on a key activity can be prevented from achieving the objectives and earning the certificate, even if their overall weighted total is otherwise high enough.
Activities can be of 2 types:
Classroom activity (or in-person activity), where grades have to be imported from some other source
Online activity selected from the course, where grades are obtained through the fulfilling of the activity in the course
Chamilo calculates each learner's overall grade based on these weights.
Setting Up the Assessment
Open the Assessments
tool from the course homepage
You will see the assessments overview, initially empty
Adding Activities
Click Add online activity
Choose the type:
Test — Link a specific exercise from the course
Assignment — Link a student publication folder
Learning path — Link learning path completion
Attendance — Link an attendance sheet
Forum thread — Link a forum thread (which has to be graded manually)
Survey — Link a survey
Select the specific activity within the chosen type
Set the Weight for this activity (e.g., 30% for the midterm exam, 40% for the final project)
Set the Minimum score if applicable
Save
The total weight of all activities should add up to 100%.
Sub-Categories
For complex grading schemes, you can create sub-categories to group related activities:
Example: A "Homework" sub-category (weight: 30%) containing five individual assignments each worth 20% of the sub-category
Sub-categories let you organize the assessment hierarchically while keeping the overall calculation simple
Viewing Grades

The assessment shows a table with:
Each learner's name
Scores for each activity
The weighted total
Whether the learner qualifies for a certificate
You can sort by any column to quickly identify top performers or struggling learners.
Certificates
To enable certificate generation:
In the assessment settings, set a minimum certification score (e.g., 70%)
When a learner's weighted total meets or exceeds this threshold (and they have not failed any per-activity minimum score), they can download their certificate
The certificate is generated from a template configured by the platform administrator
See Certificates and Skills for more details.
Linking to Skills
You can associate skills with the assessment. When a learner reaches the set objectives to complete the assessment, they can either get a certificate, get a skill or both. Skills are visible on their profile in the social network space. This builds a competency record over time.
Exporting Grades
Click the Export button to download grades as a spreadsheet. This is useful for:
Sharing grades with administrative systems
Performing additional analysis outside Chamilo
Keeping offline records
Tips
Plan your weights early — Define the grading scheme at the start of the course so learners know what to expect
Use sub-categories for complex courses — Group assignments, quizzes, and participation into clear categories
Set meaningful pass thresholds — The certification score should reflect actual competency, not just participation
Check regularly — Review the gradebook periodically to ensure all activities are properly linked and scores are being recorded
