See What Your Engineering Team Can Actually Do

Codility’s Skills Intelligence gives you a validated, continuously updated view of the capabilities across your engineering organisation. It is built on what engineers demonstrate in assessments, not what they list on a CV or what a manager estimates in a spreadsheet. Use it to screen candidates on proven skills, map your existing team’s strengths and gaps, and make workforce planning decisions grounded in evidence. When hiring slows, the value does not disappear. It deepens.

For engineering leaders

Know what your team can actually do. Surface capabilities you did not know existed. Identify language and framework gaps. Staff projects on validated skills, not assumptions. Know what exists internally before you hire externally.

For engineers

Validated skills that travel with your career. Know where you stand. See where to develop. A profile based on demonstrated capability, not self-assessment.

What Skills Intelligence provides today

Everything described here is live and shipping.

Granular proficiency scoring

Evolving profiles

Org-wide dashboard

Coverage analysis

AI readiness scoring

Skills Programs

VS Code for internal assessments

AI-generated feedback

Not live today:

Actionable development guidance on every coding task. Engineers get something back, not just a score.

Most enterprise skills data comes from self-reports, manager estimates, or AI inference. Validated skills data comes from observing engineers demonstrate capability in a structured assessment environment. It tells you what someone has shown they can do, not what they claim or what an algorithm guesses.

The data quality spectrum

Low fidelity

Self-reported

Engineers list skills on profiles. Rarely updated. Poorly calibrated.

Medium fidelity

AI-inferred

Inferred from Jira, GitHub, job titles. Captures activity, not proficiency.

High fidelity

Job-simulated

Engineers demonstrate capability on realistic tasks in a structured environment.

The skills intelligence landscape is crowded, but most products serve HR buyers, rely on inferred data, or focus on learning rather than operational decisions. Skills Intelligence is designed to complement your existing stack by providing a verified data layer specifically for engineering capabilities.

Where existing tools fall short for engineering

Enterprise platforms like Workday, SAP, and ServiceNow all offer skills management capabilities. These are valuable for broad workforce planning across all departments. But they are designed for HR generalists, not for engineering leaders who need to know whether their team has sufficient depth in React Native for a mobile rebuild or enough Terraform experience to handle an infrastructure migration.

Learning platforms like Pluralsight (opens in a new tab) measure skills as a diagnostic for learning recommendations. Their Skill IQ assessments are useful for identifying learning gaps, but Pluralsight is explicit that these assessments are not designed for hiring or employment decisions (opens in a new tab).

Skills intelligence platforms like iMocha (opens in a new tab) and Workera (opens in a new tab) offer broader assessment and verification across all roles. If you need to assess skills across your entire workforce, they are worth evaluating. If your primary need is deep, validated intelligence specifically about your engineering team’s capabilities, that is where Codility is focused.

Codility as the engineering verification layer

Skills Intelligence currently integrates with Workday (OAuth 2.0), SAP SuccessFactors, BambooHR, and Personio (via StackOne), with a migration in progress that will expand coverage to 85+ HRIS integrations. Skills data can also be exported via Open API. Bulk user import supports up to 10,000 employees.

Think of it like this: your HRIS tells you that you employ 200 engineers. Codility tells you what those engineers can actually do.

When hiring volume drops, most assessment platforms sit unused. Skills Intelligence changes this: the value shifts from “who should we hire?” to “what can our team do, and where should we invest?”

You have seen this before: a downturn hits, hiring freezes go into effect, and the assessment platform you signed a contract for during a growth phase becomes shelf-ware.

Skills Intelligence breaks this dependency. When hiring slows, the questions engineering leaders face do not go away. They intensify. Which capabilities are we at risk of losing? Can we redeploy engineers from completed projects to new ones? Where should we invest limited training budget for maximum impact?

These are questions that validated skills data answers directly. And answering them becomes more urgent, not less, when hiring is not an option.

SFIA is the most widely adopted formal framework. Many organisations build custom progression frameworks. Skills Intelligence does not impose a framework. It provides the validated data that sits beneath whatever framework you use.

Codility assessments are work sample tests conducted in a realistic VS Code environment. Combined with structured interviews (also supported in the platform), this draws from the top of the validity hierarchy.

Codility-specific criterion-related validity studies with customer partners are planned for end of 2026. When we have that data, it will appear here.

Our philosophy

We are transparent about what Skills Intelligence can and cannot tell you.

Assessments provide meaningful, actionable signals. They are not infallible predictions. We think that honesty is more useful than overclaiming, and we think engineering leaders can tell the difference.

An assessment captures how an engineer performed on a specific task at a specific point in time. It is a strong signal of capability. It is not a complete profile of everything that person can do. We provide evidence to inform decisions, not automated verdicts.

What is Skills Intelligence?

A capability within the Codility platform that gives engineering leaders a validated view of the skills across their team, built on assessment performance data. It covers screening, team capability mapping, and workforce planning.
