The two specifications are tracked separately rather than merged, because a pupil sitting both WASSCE and IGCSE in the same subject is following two genuinely different specifications with different content, assessment structures and grading.
The dual-curriculum problem
A substantial part of the Nigerian private school sector delivers Cambridge alongside NERDC. Parents want both — the international qualification for its portability, the Nigerian certificate because tertiary admission at home requires it.
Operationally this is harder than it looks, and most schools handle it with duplication. Two schemes of work, two mark books, two report formats, and a pupil record that exists in two places and agrees in neither. The teacher delivering Chemistry to a class sitting both is reconciling two specifications in their head and hoping the overlap holds.
The overlap does not hold cleanly. IGCSE and WASSCE Chemistry cover much the same chemistry and assess it very differently, with different practical requirements, different command words and different mark schemes. Treating them as one thing produces pupils who are moderately prepared for both and well prepared for neither.
How Edves handles it
- Separate specification tracking. A pupil carries a coverage and mastery record against the Cambridge syllabus and against the NERDC curriculum, tracked independently rather than merged into an average.
- One pupil record. Attendance, fees, behaviour, pastoral notes and parent communication remain single. Only the academic specification layer is dual.
- Command word and format practice. Cambridge papers reward specific command-word discipline — state, describe, explain, evaluate — which is a distinct skill from the equivalent WASSCE convention and is where dual-curriculum pupils most often lose marks.
- Combined reporting for parents. One report showing progress against both, which is what parents paying for a dual programme actually want to see and what most schools cannot currently produce.
- Checkpoint and A Level supported alongside IGCSE for schools running the full Cambridge pathway.
Which pupils sit which
Not every pupil in a dual-curriculum school sits both examinations in every subject, and the decision is usually made late, informally, and on limited evidence.
Because Edves holds separate mastery records against each specification, a school can see which pupils are genuinely on track for a good IGCSE grade in a subject and which would be better served concentrating on WASSCE. That is a fee conversation as much as an academic one — Cambridge entry fees are significant, and entering a pupil who will not achieve a useful grade is a cost to the family with no return.
Reporting to parents in a dual school
Parents paying international-school fees expect reporting that reflects it, and the most common complaint is not about results but about opacity — a report that gives a grade with no indication of what it means against either specification.
Edves produces reports showing progress against both specifications with the objectives secured and outstanding, which raises the standard of the parent conversation and reduces the volume of it.
Fees, which is the other half of this
Dual-curriculum schools have the most complex fee structures in the Nigerian sector: base tuition, examination entry fees per subject per board, optional subjects, laboratory and materials levies, and often a foreign-currency component for Cambridge registration.
That complexity is where invoicing errors and parent disputes concentrate. See fees and accounting.
