Skills Validation
Take skills from maybe to measurable
Skills validation across the talent lifecycle
Replace assumptions with proof of skill, from learning and hiring to early career readiness.
Employee development
See whether learning programs led to skill improvement and use the results to evaluate training impact and ROI.
Hiring and recruiting
Verify that candidates can apply the skills they claim in job-relevant situations before making a hiring decision.
Graduate readiness
Prove university students are prepared for entry-level roles with applied skills, not just completed coursework.
One platform for complete skills intelligence
Move from inferred skills to a single, verified view of skill readiness.
Certified assessments
Measure skill proficiency without guesswork using job-relevant, standardized evaluations written by experts and validated by I-O Psychologists. Our assessments are backed by 2,800 hours of research with scoring models informed by 3 million+ skill evaluation data points.
In-depth skills reports
Turn assessment results into clear, defensible skill insight you can act on. Understand proficiency using a science-backed scoring framework developed by I-O Psychologists, break down performance by individual skill, and compare candidates, learners, or cohorts at a glance.
Learning-embedded validation
Assess skills gained through learning directly within CodeSignal courses and academies. Embed assessments at defined checkpoints to confirm learners can apply newly taught skills before progressing, then use results to reinforce concepts or advance learners.
Integrity safeguards
Protect the credibility of assessment results with built-in fraud and cheating detection. Flag issues using a Suspicion Score informed by pattern detection and telemetry, detect problematic behavior, and apply optional controls like proctoring and ID verification when needed.
Real-world simulations
Assess applied skills through tasks that reflect how work actually gets done. Evaluate technical candidates in a full IDE, measure professional skills using writing and role-play tasks, and see how candidates work with AI tools by enabling or limiting assistance.
End-to-end skill coverage
Validate skills across roles, functions, and career stages—all on one platform. Assess technical, business, and AI-related skills, align evaluations to specific roles and job levels, and measure 3,000+ skills from foundational to advanced competencies.
