Nigerian Continuous Assessment — 40% CA + 60% Exam Composition Automated
NERDC curriculum requires 40% Continuous Assessment and 60% terminal examination for Nigerian JSS and SSS students. OpenEduCat tracks every CA sub-component — class tests, assignments, projects — applies the weighting automatically, and prepares the CA records required for WAEC submission.
The Continuous Assessment Management Problem
Nigerian teachers record CA components (tests, assignments, projects, participation) in separate columns across subject exercise books and registers — aggregating them to a 40-mark CA total requires manual addition per student per subject per term.
The 40% CA submitted to WAEC must match the CA held in school records. Discrepancies between what was submitted to WAEC and what is in school files create serious problems during WAEC result verification and student appeals.
JSS and SSS have different CA structures. JSS3 CA feeds into BECE; SSS3 CA is formally submitted to WAEC. Most schools use one spreadsheet template for all levels — which cannot safely represent the different sub-component weights and submission requirements.
When a student is absent for a class test, their CA score for that component must be handled per school policy (zero, average of other scores, or medical exemption). Without a system, these edge cases are resolved inconsistently across teachers, creating fairness issues.
At the end of each term, converting the accumulated CA sub-components into a single 40-mark CA total — and then combining it with the 60-mark exam score to derive the subject total and A1–F9 grade — involves four calculation steps that most teachers do manually, each a potential error point.
How Continuous Assessment Works in OpenEduCat
Configure CA Sub-Components per Level and Subject
Administrators set the CA sub-components (class tests, assignments, projects, participation) and their weights for JSS and SSS separately. Science subjects may include practical marks; arts subjects may weight projects more heavily. Configured once per curriculum template — applied automatically to all sections.
Teachers Enter CA Marks Continuously During the Term
Subject teachers record each class test score, assignment mark, and project score as they occur throughout the term. OpenEduCat accumulates the sub-component scores and shows the running CA total (out of 40) per student — so teachers always know where each student stands mid-term.
Absent and Excused Scores Handled per Policy
When a student misses a class test, the system flags it as incomplete. The school can apply its policy: record zero, use the mean of other tests, or mark as excused if a medical note is provided. The resolution is recorded with the reason — creating an audit trail for CA disputes.
Terminal Exam Scores Added After Exam
After the end-of-term examination, exam scores (out of 60) are entered per subject per student. The system combines CA (40) + Exam (60) automatically, derives the subject total (out of 100), and maps it to the WAEC A1–F9 grade scale.
WAEC CA Submission Report Generated
For SSS3 students, OpenEduCat generates the WAEC CA submission report — the school's official CA marks per student per subject in the format required by WAEC. Coordinators review and validate before submission. The approved figures are locked and stored against the student record for audit purposes.
CA Composition — JSS (Junior Secondary School)
40% CA + 60% Exam — typical NERDC-aligned JSS component structure
| CA Component | Weight | Description |
|---|---|---|
| Class Tests | 15% | Short in-class tests held 2–3 times per term |
| Assignments / Homework | 10% | Take-home tasks graded per subject per term |
| Projects and Practicals | 10% | Subject-specific projects; lab practicals for science |
| Class Participation | 5% | Oral contributions and engagement in lessons |
| Total CA | 40% | Combined CA — 40% of subject total |
| Terminal Examination | 60% | End-of-term written exam; BECE at JSS3 level |
CA Composition — SSS (Senior Secondary School)
40% CA + 60% Exam — SSS CA includes WAEC formal submission component at SSS3
| CA Component | Weight | Description |
|---|---|---|
| Class Tests | 10% | Short tests during the term (2–3 per subject) |
| Assignments | 5% | Homework and in-class written exercises |
| Projects / Practicals | 15% | Experiments (Science), Projects (Arts/Commerce); key SSS component |
| Oral / Class Participation | 10% | Oral responses, seminar presentations, group work |
| Total CA | 40% | Combined CA — includes WAEC CA submission component |
| Terminal Examination | 60% | End-of-term exam; WAEC/NECO WASSCE at SSS3 |
WAEC CA submission note: At SSS3, the school must formally submit CA marks (out of 40) per student per subject to WAEC before the WASSCE. OpenEduCat flags the SSS3 CA records for coordinator review and generates the WAEC-formatted submission report with one action.
