Exam rankings explained: candidate totals are not pass rates

Verdict: a candidate count and a pass rate measure different things. They cannot be used interchangeably when comparing examination results.

A count gives the number meeting a stated standard. A pass rate divides that number by the relevant number of candidates, then multiplies by 100. A state with more candidates can therefore record more successful students while having a lower pass rate.

For a purely illustrative example, 800 successes among 1,000 candidates means 80%; 1,200 among 2,000 means 60%. These are invented teaching examples, not state results.

The 2026 NECO release, reported by Voice of Nigeria on 24 September, states both a national count and a percentage. State comparisons likewise need matching denominators, the same examination and the same credit requirement. This note explains the calculation; it does not rank states by pass rate.
