How do you test language skills when hiring for multilingual roles? Use a short, standardised language assessment that places every candidate on the same scale, usually the CEFR levels A1 to C2, and set a minimum level per role. Test the skills the job actually uses: speaking and listening for phone roles, writing and reading for email and documents. Run the test early in the process, so you only interview candidates who meet the bar.
Almost every CV says "fluent English". Many say "fluent Dutch" or "good German" too. For a customer service agent, a sales rep for the DACH market or a consultant who writes reports for international clients, that claim decides whether the hire works. This guide explains what a language assessment for hiring measures, how to pick the right level per role, which test formats exist and where they fit in your selection flow.
This guide is written by Selection Lab, so our own language tests are in it. We also describe other options and say when they are the better choice.
Self-reported language levels are unreliable in two directions. Some candidates overrate themselves because "fluent" sounds normal on a CV. Others, often non-native speakers who are perfectly capable, underrate themselves. Neither tells you whether someone can handle an angry customer on the phone or write a clear quote.
An interview does not solve this either. A recruiter who is not a native speaker of the language struggles to judge it. And a 30-minute conversation about someone's career is a different task from a support call or a written complaint.
A language assessment replaces the claim with a measurement. Every candidate gets the same tasks, scored the same way, on the same scale. That makes candidates comparable across countries and recruiters, and it gives you a clear reason for a decision.
Language proficiency has four core skills. A good assessment lets you choose which ones matter for the role.
Most hiring tests report results on the Common European Framework of Reference for Languages (CEFR). It runs from A1 (beginner) to C2 (near-native) and is used across Europe by employers, schools and governments. Because it is a shared scale, a B2 in Spanish means roughly the same as a B2 in Polish. Some vendors use their own scale instead, such as Pearson's Global Scale of English, and map it to the CEFR.
The most common mistake is asking for C1 everywhere. A level that is too high shrinks your talent pool without improving the hire. Start from the tasks in the role, not from a general wish for "good English".
| Role type | Main language tasks | Skills to test | Typical minimum level |
|---|---|---|---|
| Warehouse, production, hospitality | Following instructions, safety briefings, short conversations | Listening, speaking | A2 to B1 |
| Customer service by phone | Calls with customers, solving problems in real time | Speaking, listening | B2 |
| Email and chat support | Written answers, tone, accuracy | Writing, reading | B2 |
| Sales and account management | Negotiating, presenting, writing proposals | All four | B2 to C1 |
| Consultants, policy advisors, content roles | Reports, advice, formal documents | Writing, reading | C1 |
| Legal and compliance roles | Contracts, formal correspondence, precise terminology | Reading, writing, specialist vocabulary | C1, plus a specialist test |
Treat these as starting points. If your team works mostly in Dutch and uses English only for occasional emails, B1 for English may be enough. Write the level down in the job profile, so every recruiter applies the same bar.
Language tests for hiring come in two broad formats. They answer different questions, and many organisations use both.
The candidate answers open questions by speaking into a microphone and writing short texts. An AI model scores the answers on criteria a human examiner would use, such as pronunciation, grammar, vocabulary, fluency and coherence. The result is a CEFR level per skill.
This format is the best fit when speaking matters, as in call centres, sales or front desk roles. It also scales well across many languages, because the same test structure works for each one.
The candidate answers multiple-choice questions on spelling, grammar, sentence structure and reading comprehension, under a time limit. Questions get harder as the test progresses, so one test separates "can write a text message" from "can write a report".
This format is quick, cheap to run at volume and has no subjective grading. It works well as an early knockout filter for roles where written language matters. It does not measure speaking.
| Format | Measures | Best for | Limits |
|---|---|---|---|
| AI-scored spoken and written test | Speaking, listening, reading, writing, scored to CEFR | Phone roles, international hiring, many languages | Needs a microphone and a quiet moment |
| Multiple-choice written test | Spelling, grammar, sentence structure, reading comprehension | Fast knockout for written roles | Does not measure speaking |
| Certificate exam (for example Cambridge) | Selected skills, formally certified | Roles that require proof for a visa, regulator or client | More time and cost per candidate |
Selection Lab offers both formats, so you can match the test to the role.
The Language Test measures speaking, writing, reading and listening in one flow of about 10 minutes. Candidates answer scenario-based questions, and the AI scores pronunciation, vocabulary, grammar, fluency and coherence. Each candidate gets a CEFR level from A1 to C2 plus detailed feedback. You choose per vacancy which skills to test, so a call centre role can focus on speaking and an email support role on writing. The test is delivered with our partner Hallo.ai and works in more than 60 languages, which gives you one yardstick when you hire in several countries. The AI scores. Your team makes the hiring decision.
For written language at work level, Selection Lab has short multiple-choice assessments in Dutch, English, German, French, Spanish, Italian, Portuguese and Finnish. Each takes about 15 minutes, has three difficulty levels in one test and runs under a fixed time limit, so you measure pace as well as knowledge. The score appears in your dashboard straight away. The Dutch Language assessment, for example, covers spelling, grammar, sentence structure and reading comprehension.
For legal and corporate practices there is a separate Legal English assessment. In 20 questions it tests contract terminology, procedural language, nuances between near-synonyms such as "may" and "shall", and formal correspondence.
Language tests work best when they are part of the first conversation with a candidate, not a separate step a week later. The Screening AI agent contacts applicants over WhatsApp, asks your knockout questions and sends the language test in the same chat. Candidates who meet the level can book an interview right away. Customers report 27% less drop-off and 15 minutes saved per applicant. Most teams are live in 2 to 10 weeks, and data is stored in Frankfurt.
Selection Lab is not the only route, and sometimes another tool fits better.
Products and language coverage change. Check the current scope with each vendor before you decide.
A language requirement must be relevant to the job. Asking for native-level Dutch for a role that needs basic instructions can exclude candidates without a good reason. Tie every requirement to concrete tasks and document why the level is needed.
Tell candidates in advance what the test measures and how the result is used. When AI scores the test, the EU AI Act treats AI used in recruitment as high-risk, which means transparency to candidates and human oversight. Read more in our guide on bias and fairness in skill tests. Keep the final decision with a person, and make sure candidates can ask questions about their result.
A language assessment for hiring is a standardised test that measures how well a candidate speaks, writes, reads or understands a language at work level. Results are usually reported on the CEFR scale from A1 to C2, so you can compare candidates and set a minimum level per role.
It depends on the tasks in the role. B2 is a common minimum for customer contact, C1 for roles with reports, advice or formal documents, and A2 to B1 for roles that mainly involve instructions and short conversations.
AI scoring of spoken language is widely used by test providers and scores on the same criteria a human examiner uses, such as pronunciation, grammar, vocabulary and fluency. Keep a person responsible for the hiring decision and check scores against job performance over time.
Most hiring tests take 10 to 15 minutes. Selection Lab's Language Test takes about 10 minutes for four skills, and the written language assessments take about 15 minutes.
Yes. Test each language separately and set a level per language. A candidate for a Benelux sales role might need C1 Dutch and B2 French, for example.
A certificate is useful when formal proof is required. For selection, a short test taken during the application is usually faster and gives you a current, comparable result for every candidate.
