CELTA vs Level 5 TEFL — which do you need?

DEPENDS ON THE JOB
2026 update

the short answer

A Level 5 (120-hour) accredited TEFL is accepted by most language schools worldwide and is the practical working minimum. CELTA costs more, includes live observed teaching practice, and is preferred for competitive markets, senior roles and some international-track jobs. The action: start with a 120-hour accredited TEFL for general language-school work, then check the specific vacancy or country's current preference before deciding if CELTA is worth the extra cost.

What each qualification actually involves

A Level 5 TEFL is typically a 120-hour accredited course covering grammar, lesson planning, classroom management and assessment, usually self-paced online with a final graded assessment. It's recognised by most language schools across Asia, Latin America and Europe as a solid, sufficient qualification for entry-level teaching roles.

CELTA (Certificate in English Language Teaching to Adults) is run in person or via intensive blended format, includes several hours of live observed teaching with real students, and is assessed by qualified tutors throughout. It costs considerably more and takes focused weeks rather than flexible self-paced study, but the observed-teaching component is genuinely different training, not just a longer version of a TEFL.

When Level 5 is genuinely enough

For most first teaching jobs — language centres in Vietnam, Cambodia, Thailand, many hagwons in South Korea, and general adult-education roles — a 120-hour accredited Level 5 TEFL is accepted and sufficient. Employers in these markets are usually checking for accreditation, verifiable certification and a bachelor's degree more than which specific brand of qualification you hold.

If your goal is simply to start teaching abroad within a market that's known to be flexible, spending extra money and weeks on CELTA may not change your outcome much, and that budget might be better used on visa costs, flights or a safety buffer.

When CELTA is worth the extra cost

CELTA becomes more valuable when you're targeting competitive markets, higher-paying private language schools, corporate training contracts, or roles where you'll eventually want to train or manage other teachers. Some employers explicitly prefer or require CELTA (or Trinity CertTESOL) for senior teaching positions.

It's important to note that international schools are a separate case entirely — they generally require a recognised teaching licence or PGCE, and neither a Level 5 TEFL nor CELTA alone typically qualifies you for those roles. Check the current requirements of any specific vacancy, since standards and preferences do shift over time.

what people actually ask

FAQs

Is CELTA better than a Level 5 TEFL?

Not universally 'better' — CELTA includes observed teaching practice and suits competitive or senior roles, while a Level 5 TEFL is accepted for most standard language-school jobs at lower cost and time. Which is right depends on your target job and country.

Do I need CELTA for South Korea or Vietnam?

Generally no. Most hagwons and Vietnamese language centres accept a 120-hour accredited Level 5 TEFL alongside a degree. CELTA can help at more competitive or higher-paying schools but isn't a standard requirement in these markets.

Is CELTA required for international schools?

No, international schools typically require a recognised teaching licence or PGCE rather than CELTA or a TEFL alone. Neither certificate replaces qualified-teacher status for most international school positions.

How much more does CELTA cost than a Level 5 TEFL?

CELTA costs considerably more because it includes tutor-led observed teaching and intensive assessment over several weeks. Typical accredited online Level 5 courses are often a few hundred pounds/dollars on promotion by comparison.

Can a Level 5 TEFL be rejected anywhere CELTA wouldn't be?

It's possible in highly competitive markets or specific senior roles where an employer states a preference for CELTA or Trinity CertTESOL. Always check the specific vacancy's stated requirement rather than assuming either qualification is universally accepted.
