Evaluate Environmental Impact Assessor candidates across 4 weighted areas: outcomes that landed, stakeholder facilitation, regulatory and policy command, and evidence and reporting. Outcomes that landed leads at 30%, so ask which schemes they took through screening, scoping and consent: wind farms, highways, quarries. Check chapters they authored and whether the Environmental Statement. Use the rubric to compare role-specific evidence consistently.

TL;DR
For outcomes that landed, look for evidence the candidate names consented schemes, the chapters they owned, and how their assessment held up under regulator scrutiny and Regulation 25 requests. For stakeholder facilitation, look for evidence the candidate describes converting a hostile consultee objection into agreed mitigation or a signed statement of common ground before submission.
Apply the written 1–5 anchors to every answer, record the evidence behind each rating, and use the factor weights to reach a consistent overall assessment.

What to assess and how to score it
Review the evidence signals before interviewing. Then use the anchored descriptions—not instinct alone—to choose the score that best matches each answer.
01
Evaluation factor
Outcomes that landed
30% weight
Ask which schemes they took through screening, scoping and consent: wind farms, highways, quarries. Check chapters they authored and whether the Environmental Statement survived determination without major further information requests.
Evidence to listen for
Names programmes or initiatives that were adopted, funded, or delivered
States their own role rather than the department's
Gives measured reach or impact
Distinguishes work that landed from work that stalled, and explains why
Five-point scoring guide
1
Poor
No delivered work; describes intent and process only.
2
Needs Improvement
Involved in initiatives but cannot say what resulted or what they owned.
3
Satisfactory
Real delivery with adequate ownership; impact described loosely.
4
Very Good
Named outcomes with clear personal scope and some measures.
5
Excellent
Names consented schemes, the chapters they owned, and how their assessment held up under regulator scrutiny and Regulation 25 requests.
02
Evaluation factor
Stakeholder facilitation
25% weight
Probe how they ran statutory consultee engagement with Natural England, the Environment Agency and local planning officers, plus public exhibitions where residents challenged noise, traffic or landscape findings.
Evidence to listen for
Brings a real contested case, not a philosophy of engagement
Names the competing interests and the resolution method
Uses concrete engagement formats and can point to input that changed a decision
Treats every group as legitimate
Five-point scoring guide
1
Poor
Diplomacy-speak with no case attached, or contempt for one group.
2
Needs Improvement
Recalls conflict but no method; engagement is a box to check.
3
Satisfactory
Real case and workable approach; resolution thin on specifics.
4
Very Good
Names the tension and method; cites engagement that shaped the outcome.
5
Excellent
Describes converting a hostile consultee objection into agreed mitigation or a signed statement of common ground before submission.
03
Evaluation factor
Regulatory and policy command
25% weight
Test command of the EIA Regulations 2017, Habitats Regulations Assessment triggers, WFD compliance and relevant guidance such as IEMA, GLVIA3, DMRB LA104 or CIEEM ecological methods.
Evidence to listen for
Names the statutes, funding rules, and processes they have worked under
Explains how those requirements sequenced their work
Owns the compliance thinking rather than deferring it entirely
Knows where the discretion sits
Five-point scoring guide
1
Poor
Outsources all regulatory thinking; cannot name a framework.
2
Needs Improvement
Generalities about compliance; no sequencing or named rules.
3
Satisfactory
Knows the main frameworks; sequencing described loosely.
4
Very Good
Names relevant frameworks and how they shaped a timeline.
5
Excellent
Cites the specific regulation or guidance driving a judgement call, including when screening concluded no significant effects and why.
04
Evaluation factor
Evidence and reporting
20% weight
Look for how they handled baseline data gaps, cumulative effects assessment, significance matrices, and GIS or noise modelling outputs used to evidence conclusions in the Environmental Statement.
Evidence to listen for
Uses data to choose between options, not to justify a decision already made
Names the sources and methods behind their numbers
Reports to funders, councils, or the public in terms those audiences can use
Tracks whether the intervention worked
Five-point scoring guide
1
Poor
No use of evidence; decisions are assertion.
2
Needs Improvement
Cites data but cannot explain its source or limits.
3
Satisfactory
Uses evidence competently; evaluation after the fact is thin.
4
Very Good
Evidence drives choices and is reported clearly to lay audiences.
5
Excellent
Explains a defensible significance conclusion with named survey data, model outputs, and honest treatment of uncertainty and residual effects.
