Need for Achievement
a stable disposition to strive for success, master tasks, and attain a high standard of excellence
§1The Principia rendering
A copyright-clean measure of this construct, authored by Principia and free to use — the one we can show in full.
Predicted psychometrics. These 11 items carry a design grade of A (avg design score 96/100) from the item-design model — an estimate pending calibration, not a measured reliability. Real responses (via deployment) sharpen it toward measured, which is what the licensing model collects.
§2The established instruments
What the field already uses — named and cited, not reproduced (item wording is copyrighted and withheld pending clearance).
- Manifest Needs Questionnaire — Steers and Braunstein, 1976
- Work Preference Questionnaire (WPQ) — Fineman, 1975a
§3The math on what we know
Synthesized priors from the live registry: pooled r, studies (k), total N, top study grade, and heterogeneity. Rows flagged for heterogeneity or single-study evidence are directional, not settled — read them as a central tendency.
