1. What a Person Specification Is
A person specification describes the who of a role — the attributes, knowledge, skills, experience, behaviors, and values that an ideal candidate should possess, beyond just the tasks of the role. It complements the role description by making clear what qualities one must bring to perform safely and well.
A strong person specification distinguishes between essential (must-have) and desirable traits, grounded in the realities of the role.
2. Why It Matters in Managing SAM Risk & Defensibility
Within a safeguarding context, a well-constructed person specification is a control in itself. It:
- Focuses evaluation on risk-relevant qualities, not just technical skills — e.g., boundary judgment, willingness to escalate uncertainties, relational transparency.
- Reduces selection uncertainty by clarifying what distinguishes a safe hire from others.
- Enables defensibility: when a hiring decision is questioned, you can point to what criteria were pre-approved, how candidates matched or failed them, and that decisions weren’t arbitrary.
- Guides screening and interviewing — panels can tailor questions and assessments to what you say matters.
- Signals seriousness and transparency to applicants — making expectations explicit up front helps filter for alignment.
3. Core Responsibilities / What Should Be Included & Done
Below are what a person specification must include and how using it well reduces SAM uncertainty and supports defensibility.
- Define essential vs. desirable criteria Decide which traits or experiences are non-negotiable (essential) and which are helpful (desirable). Essential criteria become filters; desirable ones become differentiators.
- Include both technical and behavioral/relational attributes Roles involving contact with vulnerable people must include non-technical criteria: e.g., emotional maturity, ability to manage ambiguity, comfort seeking advice, and integrity under pressure.
- Tie criteria to role risk exposures If the role involves unsupervised time, one-on-one contexts, travel, or transitions, include criteria reflecting those exposures (e.g., “experience working under supervision,” “demonstrated escalation in uncertain situations”).
- Use measurable, observable language Avoid vague terms like “good communicator.” Instead: “able to de-escalate conflict in conversation” or “has handled escalation protocols with clients in prior role.” Provide examples or behavioral anchors.
4. Fit-for-Purpose Criteria
Use Jigsaw’s three lenses to vet your person specification:
- Strategic Fit
- Does the specification reflect safeguarding priorities and mission values?
- Are criteria tied to role risks and organizational goals?
- Operational Fit
- Are the criteria assessable with available tools (interviews, tests, references)?
- Is it realistic for panelists to apply them consistently?
- Experiential Fit
- Do candidates perceive the specification as fair and clear?
- Do panelists trust and feel confident using it?
- Can you explain the criteria in plain language to stakeholders?
5. Indicators of Effectiveness & Warning Signs
Success Indicators
- Candidate shortlists and assessments closely reflect the specification (not undisciplined ad hoc additions)
- Panels rarely debate the meaning of a criterion mid-process
- Hires reliably demonstrate the expected behaviors and boundary alignment
- Fewer post-hire surprises or misalignments
- The specification evolves over time to reflect new risks
Warning Signs
- Panelists reinterpret criteria in different ways
- Criteria are vague or overlapping
- The specification is altered mid-process
- Decisions rely more on charisma or “gut feel” than matching criteria
- Applicants complain about mismatch between advertised traits and actual role expectations
