Why Testing Editing Skills Matters

Hiring an editor based on CV and interview alone is one of the costliest mistakes a publishing or communications team can make. Editorial skill is technical, measurable, and highly variable — two candidates with identical CVs can produce dramatically different work under the same conditions. The only reliable way to find out who can actually do the job is to test them before you hire.

Editorial aptitude tests give HR teams objective, comparable data at scale. Instead of relying on subjective impressions from a cover letter or a portfolio that may have been polished over months, a structured test captures real-time performance under controlled conditions. The result is a hiring decision grounded in evidence, not instinct.

What Editorial Skills Can Be Tested

A comprehensive editorial assessment covers several distinct competencies, each of which requires a different testing approach:

Copy-editing and track-changes editing

The most technically demanding editorial skill. A good copy-editing test presents candidates with a passage containing deliberate errors — grammatical, stylistic, factual, and structural — and asks them to correct it within a realistic editorial environment. The best tests use a simulated track-changes interface that mirrors the actual tools editors use in professional contexts, so you are measuring real editorial behaviour rather than abstract knowledge.

Proofreading

Proofreading and copy-editing are distinct skills, and the best candidates for editorial roles need both. A proofreading test presents near-final copy and measures a candidate's ability to spot residual errors of spelling, punctuation, consistency, and typography — the kind of errors that survive earlier rounds of editing. Proofreading speed and accuracy are both measurable dimensions.

Grammar and language accuracy

Grammar tests assess foundational language competency: subject-verb agreement, tense consistency, punctuation rules, sentence structure, and usage. A grammar test is a useful first-stage screener because it is fast to administer and gives an immediate quantitative signal about a candidate's language baseline.

Writing ability

For roles that require original writing — content editors, communications officers, editorial managers — a writing test assesses clarity, structure, tone, and vocabulary in an original response to a prompt. Writing tests introduce a subjective element that the other test types avoid, but when well-designed they provide valuable signal about a candidate's expressive range.

Industry vocabulary and terminology

This is the most frequently overlooked editorial competency. An editor working on cardiology journals needs to know what systolic dysfunction means. An editor at a legal publisher needs to distinguish between tortious liability and contractual liability. Industry vocabulary tests assess whether a candidate has the specialised knowledge to edit confidently in a specific sector — knowledge that cannot be faked under timed conditions.

How to Structure an Editing Skills Assessment

The most effective editorial hiring processes use a staged approach:

  1. Stage 1 — Grammar screener (15 minutes): Administered to all applicants. Filters out candidates below a baseline language threshold without requiring significant HR time.
  2. Stage 2 — Core editorial test (30–45 minutes): Administered to shortlisted candidates. A full editing or proofreading test that produces a percentile score against a large benchmark pool.
  3. Stage 3 — Industry vocabulary test (15–20 minutes): For specialist roles. Confirms the candidate has the domain-specific knowledge the role requires.

This three-stage structure filters effectively at each step without over-burdening candidates or HR teams.

What to Look for in an Editing Test Platform

Not all editorial testing platforms are equal. When evaluating options, HR teams should look for:

  • Percentile benchmarking: A raw score of 72% means nothing without context. A platform with a large benchmark pool — ideally 100,000+ prior candidates — can tell you whether a score of 72% places a candidate in the top quartile or the bottom half for their target role.
  • Ecological validity: The test environment should resemble real editorial work. A proofreading test that uses a basic form bears little resemblance to professional proofreading. A track-changes editing test that simulates the actual MS Word environment measures a skill that transfers directly to the job.
  • Industry specificity: Generic editing tests are useful for general roles. For specialist publishers — medical, legal, financial, technical — an industry vocabulary test is essential. Look for platforms that cover your sector in depth.
  • Instant automated reports: Manual scoring creates bottlenecks. A good platform delivers scored results to the HR dashboard immediately on test completion, with percentile rankings already calculated.

Common Mistakes When Testing Editing Skills

Even well-intentioned HR teams make avoidable errors when building editorial assessment processes:

  • Using a take-home test without time limits: Without a timer, you are measuring research and polish, not raw editorial skill. Timed tests under controlled conditions produce more reliable signal.
  • Testing only for grammar: Grammar competence is necessary but not sufficient. A candidate can score perfectly on a grammar test and still be a poor copy-editor — because editing requires judgement, not just rule-following.
  • Ignoring industry knowledge: For specialist roles, a candidate who cannot recognise the terminology of the field they are editing is a liability regardless of their general editorial ability.
  • Skipping benchmarking: Without benchmark data, you cannot interpret scores. A score of 85% on a test you designed internally is meaningless; the same score on a platform benchmarked against 130,000+ candidates tells you exactly where the candidate ranks.
