First-Year / New-Hire Attrition Rate

operationalbehavioral · attrition · rate · organization

Share of new hires who leave within their first year.

How it’s computed

Formula

new-hire separations <12mo / new hires

Measurement model

operational (a formula over systems data) — not a reflective survey scale; “reliability” here means data quality, not internal consistency

What it operationalizes

This metric measures the construct(s) below from operational data. Through them, it connects to the meta-analytic relationship network — the bridge from what you measure operationally to what the science knows.

What we know

Synthesized Bayesian priors over relationships involving this metric’s construct(s) — the meta-analytic evidence, with 95% confidence intervals and between-study heterogeneity (I²). Follow a row for the full distribution, contributing studies, and code.

The evidence

Attributed quotes from open-access papers, classified for stance against the relationship. Sourced and classified by Principia (no third-party feed) — displayable under each paper’s license.

“A realistic representation is critical for engineering as denying the agentic traits of the field would be an inaccurate representation of it—which would likely have negative consequences on retention (Earnest et al., 2011).” supports

“Research has consistently shown that realistic job previews are associated with lower turnover rates, though e ff ect sizes are modest (Earnest et al., 2011; Phillips, 1998; Premack & Wanous, 1985).” supports
