Assessment

School-Based Assessment

The record most Ghanaian schools cannot defend if questioned — and the one that now carries more weight than ever.

Direct answer
School-Based Assessment is continuous assessment conducted by the school that contributes to a learner’s overall outcomes under NaCCA and GES policy.

Edves records SBA continuously against learning indicators rather than as a column of scores, so the record is complete because it was built as the term progressed rather than assembled near a deadline.

Policy accurate as at July 2026. Ghana’s curriculum, teacher licensing and data protection frameworks are all mid-reform. Confirm the current position with the Ministry of Education, NaCCA, GES, NaSIA, NTC or the Data Protection Commission before acting on it. This page describes how Edves supports schools; it is not legal or regulatory advice.

Why SBA records fail

Ask a Ghanaian head teacher privately about SBA and you will usually hear a version of the same account. The policy is understood. The intent is accepted. And the record, in practice, is assembled in the fortnight before it is due, from teachers’ personal notebooks, partial mark sheets, and memory.

This is not a failure of professionalism. It is what happens when a continuous process is captured by a periodic act. Nobody sets out to reconstruct a term’s assessment at the end of it; it happens because there was no practical way to record it as it went.

The consequences are predictable: marks that cannot be justified if challenged, no diagnostic value at all, and a compliance exercise that consumes days and improves nothing.

What the new assessment model demands

The reformed senior high model reportedly includes group projects, individual portfolios, mid-semester and end-of-semester examinations, class and home exercises, and projects — and at basic level, national standard assessments replacing continuous class tests.

Consider that operationally. A school running six assessment types per subject per semester across a full cohort is generating several times the assessment records it previously handled. Portfolios and group projects do not reduce to a number in a mark book.

A process already failing at three or four assessment points per term will not survive at fifteen. This is the strongest practical argument for a system in Ghanaian schools right now, and it has nothing to do with AI.

How Edves handles SBA

  • Recorded as it happens, on a phone or shared staff room device, in the time a teacher actually has.
  • Held against learning indicators, not as a bare column, so the record has diagnostic value as well as compliance value.
  • Multiple assessment types — class exercises, projects, portfolios, practical work, examinations — each weighted to the school’s policy.
  • Portfolio evidence attached to the learner, with the criteria it was assessed against.
  • Group work with individual contribution recorded, which is the persistent weakness of group assessment everywhere.
  • Moderation support, so a head of department can see where one teacher’s marking diverges from another’s on comparable work.
  • Complete audit trail, so a mark can be traced to the piece of work and the date.

The moderation problem nobody looks at

Where two teachers assess comparable work in the same subject and year, their marks usually differ — sometimes substantially. This is normal and universal, and almost never examined.

It matters because SBA contributes to certification outcomes. If one class is systematically marked more generously than another, learners are advantaged or disadvantaged by teacher allocation rather than by what they can do.

Edves surfaces marking divergence between teachers on comparable assessments. Most schools running this report for the first time find something, and fixing it is a professional development conversation rather than a disciplinary one.

SBA as a diagnostic, not just a return

The reframing worth making: SBA is the largest body of evidence a school holds about what its learners can actually do. Treated as a compliance return, it produces a number. Treated as a diagnostic, it answers questions no external examination can:

  • Which indicators has this class not secured, right now, with time to act?
  • Which learners are drifting, and since when?
  • Where do two classes taught the same content diverge, and on what?
  • Which of our own assessment items do not discriminate and should be retired?

The last is unglamorous and quietly valuable. Schools accumulate questions everyone answers correctly or nobody does, and both waste assessment time.

What good looks like

A school with SBA working well can, at any point in a term, produce a defensible mark for any learner with the evidence behind it; tell a teacher which indicators to reteach next week; and generate its termly return without a compilation exercise.

Almost no Ghanaian school can currently do all three. The first is a compliance requirement, the second is where the educational value sits, and the third is the reason school leaders will actually adopt a system.

Common questions

Frequently asked

What is School-Based Assessment?

Continuous assessment conducted by the school that contributes to a learner's overall outcomes under NaCCA and GES policy, alongside external examinations.

Why do SBA records fail in most schools?

Because a continuous process is captured by a periodic act. The record is typically assembled in the fortnight before it is due, from teachers' notebooks, partial mark sheets and memory, producing marks that cannot be justified if challenged and no diagnostic value.

How does the new assessment model change SBA?

The reformed senior high model reportedly includes group projects, portfolios, mid-semester and end-of-semester examinations, class and home exercises, and projects. A school generating several times its previous volume of assessment records cannot sustain a process that was already failing at three or four assessment points per term.

How does Edves handle portfolios and group work?

Portfolio evidence is attached to the learner with the criteria it was assessed against, and group work records individual contribution — the persistent weakness of group assessment.

What is assessment moderation and why does it matter?

Where two teachers assess comparable work, their marks usually differ. Because SBA contributes to certification outcomes, systematic differences mean learners are advantaged or disadvantaged by teacher allocation rather than by what they can do. Edves surfaces marking divergence so it can be addressed as professional development.

Can SBA be used diagnostically?

Yes, and it is the largest body of evidence a school holds about what learners can do. Treated as a diagnostic it answers which indicators a class has not secured with time to act, which learners are drifting, where classes diverge, and which assessment items fail to discriminate.
