Skills Validation
Take skills from “maybe” to measurable
Give every skills-based decision a foundation you can trust: showcasing the skills people have, measured from real work, not inferred from resumes, titles, or self-reported ratings.
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, spanning 3,000+ technical, business, and AI skills across every role and level. Backed by 2,800 hours of research and scoring models informed by 21 million+ skills evaluation data points.
Skills profiles
Turn results into clear, defensible skill insight you can act on. Understand proficiency with a science-backed scoring framework from our I-O Psychologists, break performance down by individual skill, and turn each person’s validated skills into a profile you can track over time.
Validated, measurable learning
Assess skills gained through learning directly within CodeSignal courses and academies. Embed assessments at defined checkpoints to confirm employees can apply newly taught skills before progressing, then use results to reinforce concepts or advance learners.
Integrity safeguards
Protect the credibility of results with built-in fraud and cheating detection. Flag issues with a Suspicion Score informed by pattern detection and telemetry, and apply optional controls like proctoring and ID verification when needed.
Real-world simulations
When real work isn’t an option, turn to simulations to see how people would perform in a real-life setting. Evaluate technical skills in a full IDE, business skills through writing and role-play tasks, and how people work with AI by turning assistance up or down.
Skills intelligence from real work
Validate skills from the work people already do, not just point-in-time tests. CodeSignal measures proven skill across real work, from code to customer conversations to AI-assisted tasks, for an always-current view of where skills stand across your organization.
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.
Internal mobility
Find people ready for internal moves and see what skills your employees already have before filling a position externally.
Assess skills in context, not in isolation
See how people perform in realistic, job-relevant tasks, from coding and data to writing and planning. Each simulation mirrors the real work, so results reflect what someone can actually do.

2-Minute Quiz
See where your skills validation stands
The work is changing fast, and the skills behind it even faster. AI makes every applicant look strong, results are easier to fake, and the skills you validated last year may not match the job today. Take the free 2-minute quiz on how you hire, develop, and prove skills, and get your free scorecard.

Frequently asked
questions
What is skills validation?
Skills validation is the process of measuring and verifying job readiness through work artifacts and role-aligned assessments rather than relying on resumes or self-reported abilities.
How does CodeSignal validate skills?
CodeSignal validates skills through Certified Assessments and real work artifacts. Assessments measure proficiency in job-relevant tasks, use real-world simulations that show how candidates perform actual work, and have integrity safeguards that ensure assessment results are trustworthy and defensible. Skills are also continuously measured through work artifacts from tools like ChatGPT, Claude, Gemini, GitHub, Gong, Salesforce, and Slack. That could mean code for an engineer, customer calls for a seller, or AI prompts for anyone using generative AI in their day-to-day work.
What skills can CodeSignal validate?
CodeSignal validates technical skills (coding, system design, data analysis), business skills (communication, planning, spreadsheet analysis), and AI skills across 3,000+ competencies from foundational to advanced levels. All skills are assessed through role-aligned evaluations on one platform.
How does CodeSignal score skills?
Each skill is scored against a structured rubric grounded in I-O Psychology and backed by data from 21M+ evaluations. Scoring is context-aware, and the rubric and evidence behind every score are visible, so your team can review them and trust the results.
Can skills validation be used for learning and development?
Yes. Skills validation works across the talent lifecycle including employee development, hiring and recruiting, and graduate readiness programs. Organizations use validation to measure learning program impact, verify training ROI, track skill progression for internal mobility, and guide employee or student development decisions.
What makes CodeSignal skills validation reliable?
CodeSignal skills validation combines expert-written assessments validated by I-O Psychologists, real-world simulations that reflect actual job tasks, integrity safeguards including fraud detection and proctoring, and science-backed scoring frameworks.
