1.1 What Is TKT: CLIL and Who Should Take It?

Quick Answer: TKT: CLIL (Teaching Knowledge Test: Content and Language Integrated Learning) is a Cambridge English specialist exam that tests knowledge of CLIL teaching concepts — not subject expertise, not classroom performance, and not the candidate's own English level. It is a single 80-minute paper with 80 objective questions, graded in four bands rather than pass/fail.

What TKT: CLIL Actually Tests

TKT: CLIL stands for Teaching Knowledge Test: Content and Language Integrated Learning. It is one specialist module within the wider Cambridge English TKT (Teaching Knowledge Test) suite, developed by Cambridge Assessment English. CLIL itself stands for Content and Language Integrated Learning — an educational approach in which learners study a curricular subject (geography, science, history, mathematics, and so on) through a language that is not their first language, most often English.

TKT: CLIL does not test how well you know your subject content, and it does not observe you teaching a real lesson. It also does not test your personal English proficiency the way a general English exam would. Instead, it tests your knowledge of the concepts, terminology, and classroom strategies that underpin a CLIL approach: how to plan a CLIL lesson, how to scaffold subject content delivered in a second language, how learners build academic language alongside content knowledge, and how to select and adapt materials for a CLIL classroom.

That said, the exam itself is conducted in English, so candidates are expected to be familiar with everyday ELT (English Language Teaching) terminology and to have at least a CEFR (Common European Framework of Reference for Languages) B1 level of English — enough to comfortably read classroom extracts, articles, and glossary definitions under time pressure.

Who Should Take TKT: CLIL

TKT: CLIL is designed for a wide range of teachers, including:

• Subject teachers who need to teach their curricular subject (science, geography, history, etc.) in English
• English language teachers who teach curricular subjects in a second or additional language
• EAL (English as an Additional Language) teachers working within mainstream classes alongside subject teachers
• Pre-service teachers who are training to enter the profession
• Experienced teachers who simply want to refresh their teaching knowledge
• Teachers moving from another subject into English teaching

Crucially, there are no formal entry criteria. You do not need a minimum number of years of teaching experience, and you do not need any prior teaching qualification, to register. This makes TKT: CLIL genuinely open — a trainee on their first placement and a twenty-year classroom veteran can sit the identical paper.

Exam Day: What Actually Happens

On exam day, candidates sit one paper containing 80 objective (multiple-choice) questions worth 80 marks, completed within 1 hour 20 minutes (80 minutes). "Objective" tasks recur in a few standard formats: matching items (linking a term to its definition, or a technique to its purpose), standard multiple choice, and odd-one-out tasks (identifying which option does not belong with the others). Rather than writing directly on the question paper, candidates record their answers by shading boxes on a separate answer sheet using a pencil — a small mechanical detail worth rehearsing at least once with the official sample paper, since transferring 80 answers accurately under time pressure is itself a skill.

How Results Work: Four Bands, Not Pass/Fail

Unlike many licensing exams, TKT: CLIL has no pass or fail outcome. Instead, every candidate is placed into one of four bands describing their level of knowledge:

Results are issued to the candidate's exam centre approximately 2 to 4 weeks after Cambridge receives the completed answer sheets. Every candidate who sits the test earns a certificate for that module, regardless of which band they land in — and unlike many professional certifications, this certificate is valid for life; it never needs renewing.

Where CLIL Fits Within TKT

TKT: CLIL is one of two specialist modules in the TKT family. The other is TKT: Young Learners (YL), which focuses on teaching English to children. Alongside the specialist modules sit three core modules:

1. Module 1 — language and background to language learning and teaching
2. Module 2 — lesson planning and use of resources for language teaching
3. Module 3 — managing the teaching and learning process

Candidates can take any TKT module individually, in any combination, or all together — there is no required sequence and no prerequisite module. Each module completed earns its own certificate.

Cost and Scheduling

TKT: CLIL is administered throughout the year, with each authorised centre choosing its own test dates rather than following a fixed global calendar. Candidates must register at least 6 weeks in advance of their chosen date, and must do so through an authorised Cambridge English exam centre or teaching qualification centre — there is no option to book directly with Cambridge. Fees are set locally by each centre rather than fixed worldwide, and typically fall around USD 60-90 (roughly GBP 50-75) per module, though the exact figure varies by country and centre.
