Checklist: Validation Protocol and Test Script Content Peer Review

A plug-and-play pre-approval peer review checklist for the content and craft of a validation protocol and its test scripts: acceptance criteria quality, step atomicity, traceability, named test data, evidence numbering, and risk-based script rigor, run before a protocol is routed for approval signature, with a filled specimen.

Document type: Checklist

Read and copy the template below into your own quality system. It is a generic starting point for your own internal use, provided as is, with no warranty; see the Terms and License. Adopting it does not by itself create compliance.

This is a ready-to-use peer review checklist for the content of a validation protocol, not for the environment it will run in and not for what happened during execution. Replace every <<FILL: ...>> placeholder, score each line Pass, Fail, or N/A, and resolve every Fail before the protocol is routed to the formal approval signatures. A worked filled specimen follows the template. This is general guidance to adapt, not regulatory advice; verify each cited regulation against the current source before you rely on it.

Why this checklist is not a duplicate of the readiness gate

A test readiness gate confirms the environment, instruments, training, and data are ready for an already-approved protocol to be executed. This checklist runs earlier and asks a different question: is the protocol itself, the words on the page, good enough to approve. A protocol can pass every readiness item and still be a bad protocol, vague criteria, bundled steps, no traceability, because readiness says nothing about content quality. This checklist is the content gate; the readiness gate is the execution gate. Run this one first, on the draft, before the protocol goes to the author’s own review and then to formal approval. It is also distinct from a deviation record, which documents what happened during execution, and from the validation summary report, which closes the effort out; this checklist exists entirely before either of those is relevant.

1. Purpose

This checklist confirms that a draft protocol and its test scripts meet the authoring standard before they are routed for approval signature: acceptance criteria are objective and predefined, steps are atomic and unambiguous, evidence is pre-planned and traceable, requirements coverage is complete, and the rigor of each script matches the risk of the function it tests. Catching a weak criterion or a bundled step here costs a redline. Catching the same problem during execution costs a deviation, a re-execution, and a credibility question from whoever reviews the executed package later. Catching it after an inspector reads the executed protocol costs a finding.

3. Review decision

Every applicable line above scored Pass? → Approve for routing, sign this checklist, and forward the protocol to the formal approval chain unchanged
One or more Fail, and each can be corrected by the author without changing the intent of any test? → Return for minor rework, list the items, author corrects and resubmits; a full re-review is not required if the fixes are confined to the listed items
One or more Fail involving a missing requirement link, a missing risk basis for unscripted testing, or an acceptance criterion that has to be rewritten? → Return for substantive rework and a full re-review before routing

4. Acceptance criteria for this checklist

This review is complete only when every applicable line is scored, every Fail is either corrected and re-checked or explicitly accepted with a documented rationale by the reviewer, and the review decision is recorded with a name and a date before the protocol is forwarded for formal approval signature.

Reviewer sign-offK. Nakamura, Validation Lead, 2026-08-19

In this example, the protocol was well built in most respects, named data, complete evidence numbering, sound scope statement, but the reviewer caught a genuine coverage gap (item 3), a criterion that would have been unfalsifiable at execution (item 5), a bundled step that would have made any failure impossible to localize (item 6), and an undocumented rigor decision that would not have survived a question about why two functions of different risk got identical treatment (item 11). All four are cheap to fix on a draft and expensive to discover mid-execution or in front of an inspector.

Common inspection findings this checklist prevents

  • A protocol approved with an acceptance criterion so vague that the pass/fail decision at execution was effectively made by the executor’s judgment, not by a predefined bar.
  • A test step that bundled three actions, so a failure could not be traced to which action actually failed, and the deviation investigation had to guess.
  • A requirement with no linked test, discovered only when an inspector builds a traceability matrix independently and finds the gap the team missed.
  • A copy-paste protocol with a leftover reference to a different system’s screen name, exposing that the document was never actually read end to end before approval.
  • A low-risk, indirect-impact function scripted at the same depth as a Part 11 control, and a high-risk function tested unscripted, both with no written rationale, so the rigor decisions look arbitrary under questioning.
  • A protocol whose deviation and amendment handling is never mentioned, so the first time anyone thinks about how a mid-execution correction would work is during the correction itself.

How to adapt this checklist

  1. Set your review numbering scheme and require this checklist for every protocol phase, IQ, OQ, PQ, or UAT, before it leaves draft status.
  2. Assign the reviewer role to someone independent of the protocol’s author; a self-review by the author is not this checklist, even if they run through the same items.
  3. Tune item 11 to your own risk-based testing program; if your site has not adopted a CSA-aligned risk classification, mark it N/A and consider whether that is itself a gap worth closing.
  4. Keep the review decision literal, a recorded go or no-go with a name and date, never a status narrative with no decision.
  5. File the completed checklist with the protocol package so a later reviewer, or an auditor, can see that content quality was checked before approval, not only after execution.
