Communication Audit · Skill Index™

See the English skills gap across your organization.

Advanced AI testing scores every employee on all four skills — reading, listening, speaking, and writing — and adapts to each person’s role and your industry. Everyone gets one Skill Index™ from 0 to 100, mapped to their CEFR level, with results in minutes. It’s how every Achivr engagement starts.

The Skill Index™

One number anyone can read.

We test all four skills — reading, listening, speaking, and writing — turn the result into a single number from 0 to 100, then map it to Europe’s official language level. No jargon, no guessing.

From A1 to C2 — the European standard companies already trust (CEFR).

Why you can trust it

A score that holds up.

No self-assessment, no guesswork. The same AI rubric scores everyone, mapped to the European standard.

Aligned to CEFR
Every Skill Index maps to the official European level (A1–C2) — the standard your HR and L&D teams already use.
Consistent, not subjective
The same AI rubric scores every person and every skill, so a B2 in one office equals a B2 in another.
Real speaking, really scored
The speaking task is recorded, transcribed, and scored on the same rubric. Data stays in the EU; recordings are deleted after scoring.

For each person

Everyone gets their own result, and what to do next.

Each employee receives a personal Skill Index, their CEFR level, and clear recommendations tuned to their role. Click through three sample profiles.

From baseline to program

The audit is where every program starts.

We don’t test for the sake of testing. The baseline becomes the blueprint: groups formed by level and role, a study plan per group, and a re-test that proves the gain.

We propose a study plan and program for each group, tuned to your industry.

FAQ

Common questions

What is the Skill Index?
One number from 0 to 100 for each person. We test all four skills — reading, listening, speaking, and writing — and map the result to the official European level (CEFR, A1 to C2), so it's easy to read and compare.
How long does it take per person?
About 45 minutes, once, from any browser. No prep, no scheduling, no proctor.
Can we test hundreds of people at once?
Yes. That's the point. Run it across teams, departments, and offices in different countries, and get one comparable score for everyone.
Is it really AI, including speaking?
Yes. The speaking task is recorded, transcribed, and scored on the same rules as everything else, so you get real data, fast.
What about privacy?
Data stays in the EU and recordings are deleted after scoring. The diagnostic is GDPR-compliant.
Can we re-test later to see progress?
Yes. The first run is your baseline. Re-run it after training and the change shows up in the same Skill Index.
