CELTA
CELTA is a Level 5 pre-service initial teacher training qualification awarded by Cambridge University Press & Assessment, comprising a minimum 120 taught hours with six assessed hours of teaching practice and four written assignments. It is the most widely held entry-level qualification in ELT and the de facto gatekeeper to reputable adult-EFL work, with Cambridge reporting that roughly 63% of English teaching vacancies it tracked in 2025 named CELTA specifically (Cambridge English, 2026).
History
The course descends directly from the Preparatory Certificate launched at International House London in 1962 under Adrian Underhill and colleagues. From the 1970s it was administered by the Royal Society of Arts as the RSA Preparatory Certificate in Teaching English as a Foreign Language to Adults (RSA Prep Cert TEFLA). In 1988 the University of Cambridge Local Examinations Syndicate (now Cambridge Assessment) took over, relaunching the qualification as the CTEFLA; it became the RSA/Cambridge CELTA in 1996 and plain Cambridge CELTA in 2001 (StudyCELTA, n.d.; Wikipedia, 2026). In 2011 Ofqual re-registered it as the Cambridge English Level 5 Certificate in Teaching English to Speakers of Other Languages, expanding scope beyond adults to reflect the actual range of learners trainees encounter.
Structure and assessment
Every accredited centre delivers a syllabus with five topic areas (learners and contexts; language analysis and awareness; language skills; planning and resources; classroom management) across a minimum of 120 contact hours. Trainees complete six hours of assessed teaching practice with real students, spread over at least eight separate lessons and two different proficiency levels, plus six observation hours (up to three may be recorded rather than live). Four written assignments of 750 to 1,000 words cover a focus on the learner, a language-related task, a language-skills task, and a lessons-from-the-classroom reflection (Cambridge English, 2026).
Four outcomes are recorded: Fail, Pass, Pass B, and Pass A. Roughly 70% of successful candidates receive a plain Pass, around a quarter a Pass B, and only 3 to 5% a Pass A (Cambridge English, 2026). Moderation is external (a Cambridge assessor visits each course to inspect paperwork and observe at least one trainee), which is the structural feature that gives the qualification its portability.
Entry requirements and delivery
Candidates must be at least 18, hold education to a standard that would admit them to higher education, and demonstrate English at roughly C1 on the CEFR (commonly IELTS 7.0 or equivalent). Applicants complete a written pre-interview task and an interview before acceptance; the application is gatekept precisely so failure rates stay low once people are admitted.
Delivery comes in three shapes. Full-time face-to-face runs intensively over four to five weeks and is still the default format. Part-time runs three to twelve months, usually evenings and weekends. Fully online delivery, piloted before 2020 and now Cambridge-approved at scale, replicates the input sessions and teaching practice via Zoom with volunteer learners. As of 2026 fees run roughly £1,350 to £1,870 in the UK and average around USD 2,000 globally, with over 280 approved centres.
Position in the ELT qualifications landscape
CELTA sits alongside the Trinity CertTESOL as one of two Ofqual Level 5 initial certificates with externally moderated assessed teaching practice; the two are treated as equivalent by Ofqual and by most employers, though CELTA has greater name recognition outside the UK (TEFL Institute, 2025). Unregulated online "TEFL certificates," even those marketed as "Level 5," lack the observed teaching-practice component and are not accepted by employers who specify CELTA or CertTESOL. Above CELTA, Cambridge's in-service track is the Delta (Level 7, three modules), aimed at practising teachers with roughly a year of post-certificate experience; the framing of progression from certificate to diploma is mapped in the Cambridge Qualifications Ladder. Most private language schools treat CELTA as licence to teach general-English adult classes; specialised contexts (young learners, EAP, business English) expect additional training.
Critiques
The most persistent academic critique is that CELTA entrenches Presentation-Practice-Production as the default lesson shape because its compressed timescale rewards a plannable, visibly structured format that assessors can score against the 41 criteria in the syllabus. Jason Anderson (2016) notably defends PPP on exactly this ground: pre-service teachers need a workable scaffold more than they need a theoretically current one, and the SLA evidence against explicit instruction has weakened since the 1990s critiques of Ellis, Willis and Skehan. Defenders and critics agree on the descriptive claim, disagreeing only on whether the entrenchment is a bug or a feature.
A second strand, from Hobbs (2007, 2013), targets the assessment architecture around reflection. Because reflective self-evaluation is formally marked, trainees have structural incentive to strategise rather than confess: the same paperwork that is meant to generate honest diagnosis also decides whether they pass. Reflection degrades into "another box to tick," especially on four-week intensives where five to ten minutes after class is all the time available.
A third, running through the trainer-survey literature (e.g. Brandt 2006 on a "Study of CELTA Trainers' Understanding of Assessment Criterion 2g"), is descriptor drift. Grade-distinguishing words (some, generally, consistently, excellent) are interpreted inconsistently across centres and tutors, such that Pass B at one centre may equate to Pass at another despite external moderation.
None of these critiques argue for abandoning CELTA. They argue that it should be read as a competent induction into teachable classroom routines, not as a complete preparation, and that the heavy lifting of professional development begins the day the certificate is issued.
