Stratum9

“Strong candidate” (phrase): says a lot. Proves nothing.

Real behavior, scored consistently.
Not personality. Not guesswork.

Behavioral Assessments score what a candidate actually says and does in the interview against the S9 45 Performance-Based Skills™ framework across Career, Role, and Culture. No personality typing, no resume keyword matching. Just observable evidence, reviewed by a person before it counts.

What gets measured. What doesn’t.

Measured
Specific, observable behavior demonstrated during the interview
Skills tied directly to what the role actually requires
Evidence weighed by how much it matters for this role
Consistency across everything a candidate says in the interview
Not measured
Personality traits or “types”
Resume keywords or years-of-experience shortcuts
Appearance, tone, accent, or demographic signals
Anchor bias: A single impressive answer, taken in isolation

Three categories, one picture of the candidate

Career skills, Role skills, Culture skills — three lenses on the same conversation, not three separate tests.

Career skillsWhat transfers across roles, the baseline.
Role skillsWhat actually determines success in this specific job.
Culture skillsFit with how your team actually works.

Each skill scored is drawn from the ones selected for this role — and how much each category counts toward the final score is adjustable, not fixed. A senior leadership hire and an entry-level technical role shouldn’t be weighed identically.

How a skill actually gets scored

Each skill is scored from the evidence a candidate actually provides in the interview — graded from limited or unclear evidence up to strong, consistent evidence across multiple responses. A skill isn’t marked present or absent. It’s marked by how much real, specific evidence backs it up. Those per-skill scores combine — weighted by category, adjustable per role — into a single Stratum Score, with the reasoning behind each one attached and reviewable — not a black box, a shown-your-work box.

Why "more" isn't always "better"

A simple checklist can’t catch this: a skill can be over-used to the point of becoming counterproductive. More of a good skill isn’t automatically a better score — it’s read in context, the way a good manager would read it.

Example, illustrative onlyA candidate who over-indexes on empathy to the point of struggling to give direct, difficult feedback scores differently than one with balanced, situational empathy. The framework isn’t just checking whether empathy showed up. It’s checking whether it was applied well for the role.
Same logic, a different skillExtreme attention to detail can show up as an inability to prioritize or move at the pace a role needs. The goal isn’t rewarding the most of a skill — it’s rewarding the right amount, applied appropriately.

Reviewed by a human, every time

Every skill score. Every piece of supporting evidence. The final Stratum Score. All of it gets reviewed by a person before it affects a hiring decision. The assessment hands a hiring team a documented, evidence-based starting point — it doesn’t make the call for them. For the full methodology and validation approach, see Our Science and Research & Validation.

Frequently asked questions

No. Personality tests sort people into fixed types based on self-reported preferences. Behavioral Assessments score specific, observable behavior demonstrated in the actual interview — tied to what the role requires, not a general personality profile.

A high score reflects strong, consistent evidence of that skill applied within the role. The framework also accounts for a skill being over-used to the point of becoming counterproductive — so scoring rewards effective application, not just "more."

A resume match checks whether certain words appear on a document. This framework scores what a candidate actually demonstrates in real time, responding to real questions — evidence a keyword search has no way to evaluate.

Every score comes with its receipts attached.
