The Participation Plan states what the laboratory intends to do in proficiency testing across an accreditation cycle (ISO/IEC 17025 §7.7.2, ILAC-P9 §5(3), EA-4/18). Proficiency Testing records what actually happened. The Scope Coverage dialog compares the two, and that is precisely the question an accreditation body asks.

Clicking the icon on each row shows:
| Field | Description |
|---|---|
| Plan No. | Leave blank for automatic numbering |
| Title | How the plan is referred to — required |
| Cycle Start / End | The span it covers — required; EA-4/18 expects at least one accreditation cycle |
| Status | Draft, Active or Superseded |
| Superseded By | Points at the plan that replaced it |
| Participation Strategy | How the level was set against the other §7.7.1 measures |
| Review Notes | What the annual review concluded |
A new plan opens with a four-year cycle. That is a sensible starting point, not a rule — change it.
A plan is not enough as a title: it needs areas. An area is a measurement process, a characteristic and a product — for example "arsenic in soil by ICP-MS". Leave the characteristic or product blank to cover a whole method.
Per area you set how many rounds are planned each year, whether all authorised analysts must take part, and the justification for the level.
🔴 Zero planned rounds is only allowed with a documented alternative approach. Where no suitable scheme exists, ILAC-P9 §5(7) requires you to write down what the laboratory does instead. Without that text the entry is refused.
From the row action menu, Coverage compares expected rounds against those achieved, per area, and flags gaps:
| Gap | What it means |
|---|---|
| Zero rounds with no alternative | The area is neither covered nor explained |
| No participation in the cycle | Rounds were planned but none took place |
| Fewer rounds than planned | Short of the plan |
| Not all analysts participated | The area required it but not everyone was covered |
| Unsatisfactory round | There is a failed round in the cycle |
| Borderline round | z near 2 or En near 1 — the stated uncertainty may be understated |
| Round with no recorded evaluation | 30 days passed with no evaluation recorded |
| Provider accreditation unevidenced | The provider is not evidenced against ISO/IEC 17043 |
| Comparison without validity evidence | An interlaboratory comparison with no ISO/IEC 17043 application |
| Covered only by comparisons | The area rests solely on comparisons with no documented alternative |
Expected rounds are rounded down: 3.6 rounds means 3 are owed within the cycle.
Points at — this page does not stand without these:
before accreditation. That is not a system warning; that is the finding.
gap rather than a partial one.
scope area counts as uncovered.
