Cambridge Qualifications Ladder

Cambridge English publishes a continuous qualification ladder from Pre-A1 to C2, each exam calibrated to CEFR via the English Profile research programme and standard-setting panels. Recognised by 18,000+ universities, employers, and governments worldwide.

The Ladder

CEFR	Qualification	Former Name	Target	Scale	Duration
Pre-A1	Pre-A1 Starters (YLE)	—	Children ~6–8	Shield (max 15)	45 min
A1	A1 Movers (YLE)	—	Children ~7–9	Shield (max 15)	60 min
A2	A2 Flyers (YLE)	—	Children ~8–12	Shield (max 15)	75 min
A2	A2 Key	KET	Teens/Adults	120–139	~2 hr
B1	B1 Preliminary	PET	Teens/Adults	140–159	~2 hr 20 min
B2	B2 First	FCE	Teens/Adults	160–179	~3.5 hr
C1	C1 Advanced	CAE	Adults	180–199	~4 hr
C2	C2 Proficiency	CPE	Adults	200–230	~4 hr

YLE uses a shield system (5 per paper × 3 papers). All other exams use the Cambridge English Scale, a continuous 100–230 scale enabling cross-exam comparison and progress tracking.

Historical Timeline

Cambridge's testing tradition predates CEFR by nearly nine decades:

Year	Milestone
1858	Cambridge Local Examinations Syndicate (CLES) founded — initially for school examinations in Britain
1913	CPE launched — the world's first internationally recognised EFL qualification. Three candidates sat the inaugural exam; all failed. Designed to certify non-native speakers wishing to teach English in Britain. Only candidates aged 20+ could sit. Duration: 12 hours
1925–1945	Jack Roach (CLES) rescues CPE — by 1928–29 it had only 14–15 candidates per year. Roach expanded its appeal; from 1937 Oxford and Cambridge agreed to accept CPE as their English entry requirement
1939	LCE (Lower Certificate in English) launched on 21 June 1939 — sub-CPE qualification. First sitting had 144 candidates; the timing partly served refugees from occupied Europe
1975	LCE renamed First Certificate in English (FCE) — revised around communicative language teaching principles
1980	PET (Preliminary English Test) launched — Council of Europe's functional-notional framework (van Ek) influenced the design
1989	IELTS launched jointly with British Council and IDP Australia (see IELTS Overview)
1991	CAE (Certificate in Advanced English) launched — fills the C1 gap between FCE and CPE
1994	KET (Key English Test) launched — the most accessible level
2001	CEFR published; Cambridge begins formal CEFR alignment via the English Profile research programme
2002	Rebranded Cambridge ESOL (University of Cambridge ESOL Examinations)
2013	Renamed Cambridge English Language Assessment
2015	Major revision: KET → A2 Key, PET → B1 Preliminary, FCE → B2 First; Cambridge English Scale (100–230) introduced (using IRT/Rasch methods, cross-exam comparable)
2017	Renamed Cambridge Assessment English — current name

CPE is now over 110 years old. A CPE pass remains one of the most widely recognised demonstrations of mastery-level English worldwide.

Young Learners (YLE): Pre-A1 → A2

Three papers each: Listening / Reading & Writing / Speaking. No pass/fail. Every child gets a certificate.

Pre-A1 Starters — single words, basic sentence recognition, picture matching. Child responds; examiner initiates. Vocabulary ~300 words.

A1 Movers — short factual texts, simple stories, basic questions, spot-the-difference task. Vocabulary ~600 words (cumulative).

A2 Flyers — narrative tenses, simple story writing, multi-sentence instructions. The Speaking task requires the child to ask the examiner questions (picture story) — the most challenging component for Vietnamese learners. Vocabulary ~1,000 words (cumulative). Bridges directly to A2 Key.

Shield readiness indicator: 10–11+ shields total signals readiness for the next exam level.

A2 Key — B2 First: Exam Structures

A2 Key (KET)

3 papers: Reading & Writing (50%), Listening (25%), Speaking (25%) Writing tasks: guided email/note (~25 words) + picture narrative (~35 words) Speaking: personal interview + prompt-card discussion (pair format) Linguistic profile: simple connectors, limited subordination, errors frequent but non-blocking

B1 Preliminary (PET)

4 papers: Reading (25%), Writing (25%), Listening (25%), Speaking (25%) Writing: email responding to 3 bullet points (~100 words) + article or story (~100 words) Speaking: interview + photo description (long turn) + collaborative task + general discussion Linguistic profile: simple paragraph structure, present perfect/past simple distinction critical, opinions with basic justification

B2 First (FCE)

4 papers: Reading & Use of English (40%), Writing (20%), Listening (20%), Speaking (20%) Reading & Use of English has 7 parts — Parts 1–4 test grammar/vocabulary (cloze, word formation, key word transformations), Parts 5–7 test reading comprehension. Writing: compulsory essay (Part 1) + choice of article/letter/review/report/story (Part 2), 140–190 words each Speaking: interview + compare two photos + collaborative task + discussion Linguistic profile: coherent multi-paragraph argumentation, wide register range, controlled use of cohesive devices

C1 Advanced (CAE)

4 papers: Reading & Use of English (40%), Writing (20%), Listening (20%), Speaking (20%) Reading & Use of English: 8 parts — includes gapped text (paragraphs removed, matched by textual cohesion), cross-text multiple matching (comparing views across 4 short texts), open cloze (no options given), and key word transformations at C1 complexity Writing: compulsory essay (Part 1 — two input texts with contrasting views; candidate integrates, evaluates, presents own position), 220–260 words + choice of article/letter/report/review/proposal (Part 2), 220–260 words Speaking: interview + long turn comparing 3 photographs + 3-way collaborative task + extended discussion with examiner Linguistic profile: precise vocabulary in context; complex syntax deployed for nuanced meaning; formal and academic registers controlled; evaluative argument with concession and qualification; hedging natural

C2 Proficiency (CPE)

4 papers: Reading & Use of English (40%), Writing (20%), Listening (20%), Speaking (20%) Reading & Use of English: literary and abstract texts; key word transformations require complex paraphrase within tight word limits (3–8 words) with no options; open cloze without options; cross-text multiple matching requiring fine distinctions between speaker attitudes Writing: compulsory essay requiring precise register control (may specify formal, literary, or journalistic style) + choice of article/review/report/letter, 280–320 words each Listening: extended multiple matching; fine distinctions in speaker attitude, opinion, and inference Linguistic profile: near-native pragmatic competence; full stylistic range; handles literary, formal, and archival register; subtle lexical distinctions and synonymy; grammar is no longer the discriminator — stylistic precision is

CPE (1913) is the world's first EFL proficiency certificate. It remains the benchmark for mastery-level English.

The "For Schools" Variants

A2 Key for Schools, B1 Preliminary for Schools, B2 First for Schools are identical in format, level, and marking. Only the content differs: school-relevant topics replace adult workplace content. Both versions carry equal recognition.

What the Scale Grades Mean

Each exam has three pass grades: C (Pass), B (Pass with Merit), A (Pass with Distinction). A score in the next band's range earns a distinction. So a candidate scoring 140+ on A2 Key effectively performs at B1 — the certificate notes this.

Linguistic Progression Across the Ladder

Dimension	A2 Key	B1 Preliminary	B2 First	C1 Advanced	C2 Proficiency
Vocabulary	~1,500–2,000	~2,500–3,500	~4,000–5,000	~5,000–7,000	~7,000–10,000+
Grammar ceiling	First conditional, basic passive	Second conditional, past perfect, full passive	Mixed conditionals, inversion, cleft sentences	Conditional inversion, subjunctive, full modal range	All structures; grammar is a stylistic choice
Discourse	Sentences / short paragraphs	Simple paragraphs + connectors	Multi-paragraph; cohesive devices	Sophisticated cohesion; hedging; complex syntactic packaging	Native-like cohesion; stylistic variation
Writing length	25–35 words	~100 words	140–190 words	220–260 words	280–320 words
Register range	Informal	Informal to semi-formal	Informal to formal	Formal to informal; academic	Any, including literary and archaic
Cognitive demand	Transactional	Narrative + opinion	Analytical + argumentative	Evaluative + critical	Mastery + stylistic precision

Vietnamese Learner Pathway

Most private language centres in Vietnam target:

• Primary (Grade 3–6): Starters → Movers → Flyers
• Lower secondary (Grade 6–9): Flyers → A2 Key for Schools → B1 Preliminary for Schools
• Upper secondary (Grade 10–12): B1 Preliminary → B2 First

Cambridge's MOET recognition (2024): B1 Preliminary and equivalent qualifications exempt Grade 12 students from the national foreign language graduation exam. See Vietnam CEFR Landscape.
