Most people find the full-time course very intensive, mainly because of lesson planning and feedback cycles on top of input sessions. It is designed to be passable for prepared candidates, but you should not plan to work alongside a full-time course.

Do I need teaching experience to apply?

No. CELTA is designed for people with little or no teaching experience as well as for teachers without a formal qualification. Centres look for potential and language awareness at the interview.

Can non-native speakers take CELTA?

Yes. Cambridge English requires a high level of English rather than native-speaker status. Centres assess your language level during the application.

Is the online CELTA valued the same as the face-to-face course?

The certificate is the same CELTA qualification. The online format includes live teaching practice, so check with the centre how and when practice sessions take place.

CELTA Course: Format, Workload and Who It Suits

CELTA (Certificate in Teaching English to Speakers of Other Languages) is a qualification from Cambridge English for people who want to teach English to adults. It is delivered by authorised centres worldwide and is known for one thing above all: assessed teaching practice with real learners, combined with structured feedback from experienced trainers. That makes it intensive, often more expensive than an online TEFL, and widely recognised by language schools.

Course formats

Centres run CELTA in several formats. The content and assessment framework are the same; what changes is the pace.

Format	Typical shape	Good for
Full-time	Intensive course over around four to five weeks	People who can take time off completely
Part-time	Spread over several months, often evenings or weekends	People who work alongside
Online	Input online, teaching practice with learners in live online classes	People who cannot travel to a centre

Exact schedules, start dates and fees are set by each centre and vary considerably by country. The official overview is on the Cambridge English CELTA page.

Application and interview

You do not simply book a CELTA place. Centres select candidates through a short application process, usually:

An application form with a written task on language awareness, for example explaining grammar or vocabulary.
An interview, in person or online, to check your English level, your awareness of language and whether you are ready for an intensive course.
A decision and pre-course task, which you complete before the course starts.

Cambridge English sets general entry criteria, such as a high level of English and an education level that would allow entry to higher education. Centres can apply them flexibly; ask your chosen centre for its current requirements.

What happens during the course

Input sessions

Trainers cover the foundations of teaching English to adults. The emphasis is practical: everything you discuss in input should show up in your teaching soon after.

Teaching practice

You teach real classes of adult learners, usually at more than one level, and receive feedback after each lesson. Your assessed teaching practice is the heart of the course.

Observation

You watch experienced teachers and your fellow trainees teach. Observation is part of the course and helps you see different styles.

Written assignments

You complete several written assignments linked to teaching practice and language analysis.

How CELTA is assessed

Assessment is continuous. There is no final exam. Trainers assess your teaching practice and your written assignments throughout the course, and an external assessor moderates the centre’s standards. The results are graded as Pass, Pass B or Pass A, or Fail. Most employers simply want to see a pass.

The real workload

Candidates often underestimate the time outside the classroom. Beyond input sessions and teaching practice, you will plan lessons, prepare materials, reflect on feedback and write assignments. In the full-time format, evenings and weekends are usually taken up by this work. Part-time formats spread the load but need sustained discipline over months.

Practical tips:

Clear your diary for a full-time course; do not plan a side job.
Revise grammar terminology before you start.
Treat feedback as part of the course, not as criticism.
Keep all lesson plans: they help later when you write your CV.

Who CELTA suits

Career starters who want to make English teaching a profession rather than a temporary job.
Teachers aiming for competitive schools in regions where job ads ask for “CELTA or equivalent”, see teaching English abroad.
Business English trainers who want credibility with schools and agencies that place trainers, see teaching Business English.
Experienced but uncertified teachers who want a recognised qualification.

After CELTA

Most teachers work for a few years before taking the next step. For experienced teachers, Cambridge English offers DELTA, a higher-level qualification often required for senior teacher, academic management or teacher-training roles. Between the two, many teachers build their skills through shorter courses; see online CPD courses.
