Must pass K out of N subjects or checks (quorum and floor rule)
Evaluate multi-part exams, vendor scorecards, or board quorums requiring at least K passing scores plus a minimum floor on every item.
Replace combinatorial OR chains with COUNTIF >= K
Writing OR(AND(...)) to test "any 4 out of 5 modules >= 70" would require 5 separate 4-way AND clauses (and 15 clauses for 4 out of 6!).
COUNTIF(B2:F2, ">=70") >= 4 counts passing modules directly in one step. Pairing it with MIN(B2:F2) >= 50 inside AND enforces a hard safety floor so a single catastrophic 20 cannot be masked by four 90s.
| Candidate (A) | M1 (B) | M2 (C) | M3 (D) | M4 (E) | M5 (F) | Outcome |
|---|---|---|---|---|---|---|
| Candidate1 | 82 | 75 | 64 | 90 | 71 | Pass (4 >= 70, min 64 >= 50) |
| Candidate2 | 85 | 80 | 42 | 91 | 78 | Fail (min 42 < 50 floor) |
K-of-N quorum and minimum-floor formula
Reference threshold cells if pass marks or required counts vary by certification level.
=IF(AND(COUNT(B2:F2)=5, COUNTIF(B2:F2, ">=70") >= 4, MIN(B2:F2) >= 50), "Pass", "Fail")Simple K-of-N count without a floor
Omit MIN when failed optional modules carry no disqualifying floor.
=COUNTIF(B2:F2, ">=70") >= 4Inputs and interpretation
The floor rule requires all five scores to be numeric: MIN ignores blanks, so an explicit COUNT guard prevents four passing scores plus a missing score from passing. Validate the score range (for example 0–100). For a variable quorum require integer K between 1 and N. The example illustrates arithmetic, not actual certification or board-governance rules.
