Send the Cognitive Ability (IQ) from Lever in 20 minutes
When the Lever adapter ships (target H2 2026), cognitive testing will be the heaviest-lift workflow inside Lever because the test demands strong EEOC compliance documentation alongside the score itself. Lever's Feedback Forms architecture works well here: the structured form can capture not just the IQ score but also the job-analysis citation and pass-band justification, giving compliance reviewers an audit trail per candidate. The integration plan emits a structured cognitive-ability feedback form per candidate that includes overall score plus three subtest scores (pattern recognition, numerical, verbal); the form template can be customised per role to surface the cognitive-load requirement and the four-fifths-rule monitoring evidence.
Validity
General cognitive ability (g) is the strongest single predictor of job performance documented in I/O psychology — corrected ρ ≈ .51 in Schmidt & Hunter's 85-year meta-analysis (1998, Psychological Bulletin), with validity scaling up as role complexity rises. Cognitive tests also carry the highest EEOC adverse-impact risk; pair with structured-interview evidence and document job-relatedness before the first hire decision uses the score.

From Lever admin to first scored candidate.

Add the JobCannon Lever integration
From Lever admin settings, add JobCannon as an Assessment Partner. Paste your Basic Auth credentials (sandbox first, production after the first test cycle). One-time setup, takes 3 minutes.
- 2
Create a Lever scorecard mapped to Cognitive Ability (IQ) dimensions
In your job template, create a scorecard section per Cognitive Ability (IQ) dimension. Each dimension maps 1:1 to a numeric attribute on the Lever scorecard — no provider-specific glue needed.
- 3
Trigger the Cognitive Ability (IQ) on the candidate's stage transition
Add "Send Cognitive Ability (IQ)" as an automatic action when candidates enter the assessment stage. The candidate receives a co-branded Lever email and completes the 20-minute form on mobile or desktop.
- 4
View the score envelope in the candidate profile
The full Cognitive Ability (IQ) score envelope (dimensions, bands, narrative summary) lands in the Lever candidate profile within 30 seconds of submission. Recruiters review without leaving Lever.
Sample score envelope
The exact JSON shape your Lever scorecard receives back. Every JobCannon assessment uses the same dimensions[].score envelope so ranking logic stays consistent across tests.

Run a different cut on the same candidate by sending one of these from the same Lever pipeline.
Big Five (OCEAN)
personality test
Big Five conscientiousness has the strongest meta-analytic link to job performance of any single personality dimension — corrected ρ ≈ .31 across 117 studies (Barrick & Mount 1991, Personnel Psychology). The NEO-PI-R is the gold-standard instrument and forms the basis of JobCannon's 50-item adaptation, which returns five normalised dimension scores per candidate.

DISC
behavioural style assessment
DISC measures observable behaviour patterns (dominance, influence, steadiness, conscientiousness) rather than performance predictors. Its meta-analytic correlation with job performance is modest (~.10-.15, lower than Big Five). Use it inside Lever for team-fit and communication-style mapping at the interview-feedback stage, not as a primary hiring filter.

EQ (Emotional Intelligence)
emotional intelligence assessment
Emotional intelligence shows incremental predictive validity over cognitive ability and Big Five for jobs with high emotional-labour demands — corrected ρ ≈ .24 for customer-facing and people-management roles (Joseph & Newman 2010, Journal of Applied Psychology, k=88). Less informative for back-office, technical, or independent-contributor roles.

Frequently asked
When does the Lever integration ship?+
Target H2 2026. Lever's webhook + Feedback Forms pattern is more architecturally involved than the Assessment-API-native ATSes; ship date reflects that scope.
How will cognitive testing meet EEOC requirements inside Lever?+
The structured Feedback Form template will include the cognitive-ability score, the job-analysis citation (per Uniform Guidelines on Employee Selection Procedures), and the pass-band justification. Lever's audit trail captures the form template version per candidate, so compliance reviewers can retrace the basis for every cognitive-test screening decision.
Can I send the IQ test from Lever today?+
Not natively. Bridge today through the JobCannon REST API; build a thin Lever-webhook listener in your own infrastructure. Reference code on request. We strongly recommend pairing the bridge with a documented job-analysis step before the first cohort uses the score.
Which Lever roles benefit most from cognitive testing?+
Roles with high task complexity — software engineering, data science, research, finance analyst, product strategy, executive roles. Schmidt & Hunter (1998) shows validity rises with complexity: low-complexity ρ ≈ .23, high-complexity ρ ≈ .58. Skip cognitive testing for low-complexity roles.
How long does the IQ test take?+
Median candidate completion is 20 minutes on JobCannon's 30-item form. The longest assessment in the B2B catalog — candidate friction is higher but warranted when role complexity justifies the predictive lift.
How do I express interest in early access?+
Email [email protected] with your Lever organisation slug plus a note on which role families you plan to use cognitive testing on. We will help you scope job-analysis documentation as part of onboarding.
