What is CELTA? Entry Requirements, Structure, TEFL

The Certificate in English Language Teaching to Adults is the initial teaching qualification awarded by Cambridge English, part of the University of Cambridge. It is the credential language schools mean when a job advert asks for "CELTA or equivalent".

For career changers and new teachers, that is the whole point. The course assumes no classroom experience, and it is the qualification that most reliably converts into a first teaching job, a better school, and a stronger starting salary.

  • Career changers

    Moving into ELT with a qualification employers already recognize.

  • Recent graduates

    Turning a degree into a teaching career that travels worldwide.

Entry requirements

CELTA entry requirements

Cambridge sets the floor and centers apply it. Here is what each requirement is actually checking for.

  • Be at least 18 years old

    Most centers prefer candidates aged 20 or over.

  • Have a high level of English (C1 to C2)

    You need to analyze and explain language accurately, under time pressure.

  • Show you're ready for demanding work

    Academic discipline and study skills matter more than prior teaching experience.

  • Pass a pre-interview task and interview

    Centers evaluate your language awareness and course readiness.

Not sure if you meet the criteria? Check eligibility

Centers vary slightly in how they weigh these, and a strong pre-course task can offset a borderline profile. Every center still has to meet the Cambridge standard.

Syllabus

How a CELTA course is structured

Every approved center runs the same four components across a minimum of 120 contact hours.

  1. Component 1

    Input Sessions

    Trainer-led sessions on learner-centered methodology, language analysis, lesson planning, and teaching the four skills.

    • Trainer-led
    • Runs throughout the course

  2. Component 2

    Observation of Experienced Teachers

    Six hours watching qualified teachers work, live or on video, with structured tasks so you are reading lessons rather than sitting in on them.

    • 6 hours of observation
    • Guided observation tasks

  3. Component 3

    Assessed Teaching Practice

    At least six hours teaching real adult learners at two different levels, observed by qualified CELTA trainers, with feedback after every lesson.

    • 6 assessed hours
    • Two learner levels

  4. Component 4

    Four Written Assignments

    Focus on the learner, language, skills, and lessons from the classroom. Marked internally and externally moderated by Cambridge.

    • 4 assignments
    • Externally moderated

On the course

A day on a full-time CELTA

Morning input, teaching practice, feedback after lunch, a second input session, and independent study.

  1. Morning

    Input sessions

    A trainer-led session on methodology or language analysis, with the whole group working through the same material.

  2. Late morning

    Teaching practice

    You teach real adult learners, or you observe the trainees teaching before and after you and take notes against a task.

  3. After lunch

    Feedback

    A trainer-led session on what worked, what did not, and what to change tomorrow. This is where most of the learning happens.

  4. Afternoon

    Input session

    A second trainer-led session, usually on a different area of methodology or language, once teaching and feedback are done.

  5. Evening

    Independent study

    Preparing the next lesson, writing assignments, and reflecting on feedback. Full-time candidates should expect this to fill most evenings.

Part-time, online, and blended courses spread the same components across weeks or months. The total workload does not shrink, but the evenings are yours again.

Assessment

Assessment and grades

Assessment is continuous and externally moderated by Cambridge. There is no final exam to revise for.

  1. Pass

    Meets Criteria

    Meets every Cambridge assessment criterion across teaching practice and writing.

  2. Pass B

    Strong Performance

    Consistently strong performance, with real excellence in key areas.

  3. Pass A

    Outstanding Distinction

    Outstanding across the whole course. Awarded to a small minority of candidates.

Grades reflect overall performance, with teaching practice carrying the most weight. Most candidates who complete the course pass.
