Assessing English in Recruitment: Levels, Tests and Interviews

Setting an English requirement for a role starts from the tasks that role actually involves, since the Common European Framework of Reference for Languages (CEFR) grades ability from A1 to C2 across six levels grouped into basic, independent and proficient users, and a job built on reading technical manuals and writing client reports calls for a different level from one built on following simple spoken instructions. Recruiters assess this ability through recognised certificates, online tests, structured interview tasks or written exercises, each suited to different roles and different levels of assurance needed.

Certificates from bodies such as IELTS, Cambridge English, OET, Trinity College London and LanguageCert report results against band scores, grades or the CEFR scale itself, and the organisations that set rules on their use, including UK Visas and Immigration and the healthcare regulators, commonly treat results as reliable for around two years before asking for fresh evidence. Building consistency into the assessment process, and offering structured support where a strong candidate falls slightly short of the target level, lets recruiters make sound decisions without turning English into an unnecessary barrier to hiring.

How should a recruiter set the required CEFR level for a role?

The level required for a role should follow from what the job asks a person to read, write, say and understand, since the CEFR is built around can-do descriptors for each of its six levels, as set out by the Council of Europe, which groups A1 and A2 as basic user, B1 and B2 as independent user, and C1 and C2 as proficient user. A role built on scripted, repetitive spoken exchanges sits at a different point on that scale from one built on negotiating contracts or writing technical documentation.

Regulated professions show how this task-based approach works in practice. The Nursing and Midwifery Council sets a minimum IELTS score of 7.0 in reading, listening and speaking and 6.5 in writing, or grade B in the equivalent OET components, reflecting the communication demands of clinical practice, while the General Medical Council sets its bar higher still, requiring an overall IELTS score of 7.5 with a minimum of 7.0 in each skill. Recruiters outside regulated sectors can apply the same logic by mapping their own role's tasks onto the CEFR descriptors before choosing a level to test for.

What are the options for assessing a candidate's English?

Four broad methods let recruiters check English ability, and most roles are well served by combining more than one, since a single data point rarely covers every skill a job needs. Recognised certificates give an externally verified, standardised result. Online or computer-based tests give a quick, structured indication of level. Structured interview tasks let an assessor observe spoken English close to the conditions of the job, and written tasks show how a candidate handles the kind of writing the role actually requires.

• Recognised certificates: IELTS, Cambridge English, OET, Trinity College London and LanguageCert, each reporting against the CEFR
• Online or computer-based tests: quicker screening tools, useful for an initial filter and less suited to a final decision.
• Structured interview tasks: role-play or scenario questions scored against a fixed set of criteria
• Written tasks: drafting an email, summarising a document or completing a short report relevant to the role

What do certificates such as IELTS and Cambridge English report?

IELTS reports a band score from 0 to 9 for each of listening, reading, writing and speaking, together with an overall band calculated as the average of the four and rounded to the nearest half band, with bands from around 4 to 9 aligning to CEFR levels from B1 up to C2. Cambridge English exams such as B2 First and C1 Advanced report a score on the Cambridge English Scale for each skill and overall, alongside a grade and the corresponding CEFR level, since each exam is designed around a particular section of that scale.

OET, aimed at healthcare professions, grades each of its four sub-tests separately on a scale of 0 to 500 with a corresponding letter grade from A to E; it does not produce a single overall score, since regulators such as the NMC and GMC set their own minimum grade for each component. Trinity College London's Integrated Skills in English and Graded Examinations in Spoken English are calibrated across all six CEFR levels, and LanguageCert reports both a score on its own Global Scale and the corresponding CEFR level on its certificates.

How long are English test results treated as valid?

Validity periods are set individually by the bodies that rely on the results; there is no single universal rule, and two years is the period recruiters will meet most often. UK Visas and Immigration treats a Secure English Language Test result as valid for two years from the date it was awarded, IELTS itself recommends that its results be treated as valid for two years, and the NMC applies the same two-year window to the IELTS and OET evidence it accepts for registration.

OET sets no fixed validity period of its own, leaving the length of time a result stays current to the authority relying on it, such as a particular regulator or employer. LanguageCert certificates carry no expiry date on the document itself, though an organisation using the result may still choose to apply its own cut-off. Recruiters setting an internal policy can reasonably take two years as a working default, checking it against any sector-specific rule that applies to the role.

How can recruiters keep assessment fair and consistent across candidates?

Consistency comes from testing every candidate for a given role against the same tasks and the same scoring criteria, since a structured approach removes much of the variation that creeps in when interviewers judge English impressionistically. Using the CEFR's can-do descriptors as a scoring rubric keeps the assessment tied to what the role actually needs, since it points assessors back to concrete tasks a candidate can or cannot do.

Separating accent and pronunciation from comprehension and task performance matters here, since a candidate can communicate perfectly well for the role while sounding different from the assessor, and treating the two as the same thing risks screening out capable candidates for reasons unrelated to the job. Briefing everyone who conducts an assessment on the same criteria, and recording scores against that criteria instead of an overall gut feeling, gives a hiring decision a clearer paper trail if it is ever questioned.

How can employers support a hire whose English is slightly below the target level?

A candidate who is strong on every other measure but sits just below the target CEFR level is often worth supporting into the role, provided the gap is pinned down to specific skills using the CEFR descriptors for the target level. Comparing a candidate's certificate or assessment result skill by skill against those descriptors shows exactly where the gap sits, whether that is written accuracy, spoken fluency or listening under pressure.

A training plan focused on the specific skill identified, such as written accuracy or listening under pressure, gives a narrow gap a clearer path to closing than an unfocused general English course. Building in a review point after a set period, using the same type of assessment the candidate was originally tested with, gives both employer and employee a way to check progress, and pairing this with on-the-job support, such as a colleague reviewing written work in the early weeks, helps close the gap without treating the original score as fixed.

English training for staff with Taylor Tuition

Employers who come to us usually have a handful of staff at different levels and a deadline set by a role, a relocation or a registration body, so programmes start with a level check for each person and are then run one-to-one or in small groups of colleagues at a similar level.

English for adults is taught one-to-one or in small groups, at every level from beginner (CEFR A1) to proficient (C2), online or in person in central London. Fees start from £50 per 50-minute session and depend on tutor level, there is no registration fee and the initial consultation is free. Employers can book programmes for staff and are invoiced directly, and we reply to enquiries within one working day with tutor recommendations.
