Canada Hidden Hiring Signals Index 2027
CHHSI measures the gap between what employers say they need to know about candidates before hiring and what traditional hiring processes can reliably reveal.
What the index measures
It is a descriptive workforce research benchmark — not an employer-quality score, candidate score or AI-adoption ranking.
What information do you wish you knew about a candidate before hiring — but the traditional résumé and interview rarely reveal?
Four dimensions
| Dimension | Definition | Purpose |
|---|---|---|
| Signal prevalence | % selecting a signal in their top three | How widespread the need is |
| Signal priority | % naming it the single most important signal | How often it becomes decisive |
| Visibility gap | Inverse of current pre-hire assessability | How poorly the current system can see it |
| Decision value | Expected improvement if assessed reliably | How valuable it would be to close the gap |
Initial 2027 score
Freeze the final scoring rule before publishing the formal benchmark. The pilot should test wording and category coverage, not optimize weights after seeing results.

Sample maturity
| Phase | Target | Use |
|---|---|---|
| Pilot | 100 complete employer responses | Test wording, completion and taxonomy. |
| Calibration | 300 complete responses | Test sector and company-size patterns. |
| 2027 descriptive benchmark | 500–750+ complete responses | Stronger national descriptive reporting and sector cuts. |
Publication safeguards
Do not call the index nationally representative unless a defined sampling frame and weighting method justify that claim. Avoid public percentages for very small segments. Use open-text quotations only according to the contributor’s attribution choice.
