FluencyScreen vs EF SET: can a free English test work for hiring?
EF SET is a free, CEFR-aligned English test that gives individuals a shareable certificate. FluencyScreen is a spoken English screen that recruiters send and score. They overlap on the CEFR scale and almost nowhere else, which makes the choice easier than it looks.
You will see EF SET on candidates' CVs, and you will see it recommended in forums as the free way to test English before hiring. Both are reasonable. But EF SET was built for learners to measure themselves, and using it as a hiring screen means accepting things a recruiter usually would not. Here is the honest comparison.
The short version
- EF SET is free, aligned to the CEFR, and gives the test taker a certificate they can link from LinkedIn. The 50-minute version covers reading and listening; the 90-minute version adds writing and speaking. EF states that identity is not checked and the online test is not proctored.
- FluencyScreen is a 10 to 15 minute voice interview you send to a candidate. The transcript is scored on the CEFR scale across six skills, and you get the recording, the transcript and a confidence indicator. The candidate does not see the result; you do.
Side by side
| FluencyScreen | EF SET | |
|---|---|---|
| What it is | A speaking interview the recruiter sends to a candidate; the result goes to the recruiter. | A free online English test individuals take to get a certificate for their CV or LinkedIn profile. |
| Who runs it | You create the link, choose the topic and voice, and read the report. The candidate does not see the score. | The candidate, on their own time, on efset.org. Companies can arrange custom links or proctored sessions. |
| Skills | Speaking only: grammar, vocabulary, fluency, coherence, comprehension and task completion, scored from the transcript. | 50-minute test: reading and listening. 90-minute test: reading, listening, writing and speaking. |
| Candidate time | Usually 10 to 15 minutes. | 50 or 90 minutes depending on the version. |
| Identity and integrity | The full recording is saved so you hear the candidate yourself. Follow-ups are generated live, and signals like tab-switching are logged. Not a proctored exam. | EF's FAQ states identity is not checked and tests taken on the site are not proctored. Proctored sessions can be organized for companies. |
| Result | CEFR level (A1 to C2) with six skill scores, a confidence indicator, the transcript and the recording, in your dashboard. | A CEFR-aligned score per skill and a shareable certificate URL. One certifying session per 90 days; a retake updates the certificate. |
| Pricing (public) | Free for 2 interviews a month; $29/month for 30; $99/month for 150. | Free for individuals. |
EF SET details are taken from efset.org, including its FAQ, as of September 2026 and may change. EF also sells assessment products for companies that differ from the free test.
Self-assessment versus screening
The core difference is who the test is for. EF SET's job is to tell a learner where they stand. It is honest about that: the FAQ says it is "designed primarily as a tool for individuals to evaluate themselves." That design shows up everywhere a recruiter cares about. Anyone can take it, on any device, with anyone in the room, and retake it every 90 days until the certificate says what they want it to say.
A hiring screen has the opposite requirements. You choose when it happens, you know who took it, and you get the evidence. FluencyScreen is built that way: you create a one-time link, the candidate opens it in a browser and talks to the AI interviewer, and the recording plus transcript land in your dashboard with the CEFR level and six skill scores. You can replay the answer to the follow-up question and hear for yourself whether the level is real. For how to read that report, see reading the report.
The speaking gap
Most EF SET certificates you will see come from the 50-minute test, which measures reading and listening. That is a fine proxy for general level and says nothing about speech. The four-skill version does include speaking, scored by AI, but it costs the candidate 90 minutes. In a competitive market that is a real drop-off risk for exactly the candidates you want. A ten-minute conversation gets you the spoken evidence without asking for the afternoon. On why written or recognition scores overstate speaking, see how to assess spoken English.
When EF SET is the better choice
- You have no budget at all.A free, CEFR-aligned certificate is a much better filter than "fluent" on a CV.
- Candidates already have one. If the CV links an EF SET result, use it to decide who gets to the next step. It costs nothing to look.
- You are placing existing staff into training. For internal level checks where identity is not in question, a free four-skill test is hard to beat.
- Reading and listening are the job. For roles that read documentation or follow calls but rarely speak, the 50-minute test measures the right skills.
When FluencyScreen is the better choice
- You need to know it was them.The recording is the candidate's own voice answering unscripted follow-ups, and it is yours to replay.
- The role is spoken. Support, sales, anything on a call. You want the speaking level, with evidence, in ten minutes.
- You want a consistent process. Every candidate gets the same kind of interview, the same scoring rubric and the same report, which is what makes results comparable across a hiring round.
- You want the result without the candidate steering it. The score goes to you, not to a certificate the candidate can retake and curate.
A practical way to decide
Treat EF SET as a reason to shortlist and FluencyScreen as the screen. Accept a certificate as evidence the candidate has taken English seriously, then send your own link to hear the level for yourself before scheduling a human interview. The free FluencyScreen tier covers two interviews a month, which is enough to try the workflow on your next opening. For the broader criteria, see what to look for in a pre-employment English test.
Frequently asked questions
- Is EF SET valid for hiring?
- As a signal, yes; as a screen, with caution. EF SET is calibrated to the CEFR and widely recognized, but EF's own FAQ says it is designed primarily for individuals to evaluate themselves, identity is not checked, and tests taken on the site are not proctored. A certificate on a CV tells you the level someone reached on some unsupervised attempt. It does not tell you that the person in front of you is the one who took it.
- Does EF SET test speaking?
- The 50-minute EF SET tests reading and listening only. The 90-minute four-skill version adds writing and speaking. If a candidate shows you an EF SET certificate, check which version it was; the common one has no speaking component at all.
- Why pay for FluencyScreen if EF SET is free?
- Because you are buying a different thing. EF SET is free for the candidate and produces a self-reported certificate. FluencyScreen is a screen you control: you send the link, the candidate speaks for 10 to 15 minutes, and you get the CEFR level, the per-skill scores and the recording. The free tier covers 2 interviews a month; paid plans start at $29/month. The cost you are avoiding is a phone screen with someone who cannot hold the conversation.
- Can I ask candidates to take EF SET instead?
- You can, and some companies do it as a pre-filter. Expect two issues: the four-skill test takes 90 minutes, which loses good candidates who have other offers, and you cannot verify who sat it. A practical middle path is to accept an EF SET certificate as a reason to shortlist, then send a FluencyScreen link to hear the shortlist speak.
