Teaching English as a Foreign Language is one of the most flexible and geographically liberating careers available to UK graduates and non-graduates alike. A 120-hour TEFL or TESOL certificate is accepted as the standard entry qualification by language schools, international employers, and online teaching platforms across the globe. Whether your ambition is to spend a year teaching in South Korea, build a thriving online tutoring business from your living room, or land a full-time teaching position in Spain or the UAE, a TEFL certificate opens the door. This guide explains everything you need to know – from choosing the right qualification to calculating what you can earn in different markets – so you can plan your TEFL career with confidence.
Key takeaway: A 120-hour TEFL or TESOL certificate is the industry-standard minimum qualification for teaching English abroad or online. No degree is required for many online platforms and some in-country markets, though a degree significantly expands your options in competitive destinations such as South Korea, Japan, and the UAE.
What does a TEFL teacher do?
TEFL teachers (Teaching English as a Foreign Language) teach English language skills to students whose first language is not English. The work varies enormously depending on the setting: a TEFL teacher in a private language school in Barcelona might spend their days teaching grammar and conversation to adult professionals; one working in a South Korean public school might teach phonics and reading to primary-age children; and an online TEFL teacher on a platform such as EF or Cambly might deliver one-to-one conversation lessons to business executives in China. The common thread is communication – helping people develop confidence and competence in English for academic, professional, or personal purposes.
Day-to-day responsibilities typically include:
- Planning and delivering English language lessons to individuals or groups at a range of levels
- Assessing students' current language level and identifying areas for development
- Creating or adapting lesson materials to suit different learner needs and interests
- Providing structured feedback on speaking, writing, reading, and listening skills
- Using a range of teaching techniques including role play, discussion, and communicative activities
- Managing classroom dynamics and maintaining an engaging, supportive learning environment
- Completing administrative tasks such as attendance records, progress reports, and lesson plans
- Continuing professional development through observation, peer feedback, and further training
TEFL destinations and teaching contexts
Asia: South Korea, Japan, Vietnam, China
Asia remains the world's largest market for English language teachers. South Korea's government-funded EPIK (English Program in Korea) and public-private GEPIK schemes offer structured contracts with flights, accommodation, health insurance, and end-of-contract bonuses on top of a monthly salary – typically around 2.0–2.7 million Korean Won (approximately £1,150–£1,550 per month) plus benefits. Japan's JET Programme offers similar arrangements. Vietnam has grown rapidly as a TEFL destination, offering lower formal salaries but a lower cost of living and a vibrant expatriate teaching community. These destinations generally require a degree for visa and employer purposes as well as a TEFL certificate.
Europe: Spain, Germany, France, Italy
Spain and Italy are popular European TEFL destinations for UK passport holders, though post-Brexit working rights have added complexity for those seeking long-term positions. Spain in particular has a large private language academy sector and a significant demand for native English-speaking teachers. Monthly salaries in Spain typically range from €900–€1,400, which reflects the lower cost of living. Germany and the Netherlands offer higher salaries – often €1,600–€2,400/month for qualified teachers in the corporate language training sector. Some European positions are more accessible with a UK passport under specific visa categories; always check current visa requirements.
Middle East: UAE, Saudi Arabia, Qatar
The Middle East – particularly the UAE, Saudi Arabia, and Qatar – offers some of the highest-paying English teaching positions in the world. International school teachers and EFL teachers at universities and government institutions can earn £2,000–£4,000 per month tax-free, often with accommodation, flights, and health insurance included. These positions typically require a degree and a TEFL or teaching certificate, and competition is strong. Positions at international schools may additionally require QTS (Qualified Teacher Status) or an equivalent national teaching qualification.
Online TEFL teaching
Online TEFL is the fastest-growing segment of the market and the most accessible entry point for UK-based teachers who are not yet ready to relocate. Platforms including EF Education First, Cambly, italki, Preply, and VIPKID (primarily serving Chinese students) connect teachers with learners worldwide via video call. Hourly rates vary: Cambly pays around $10.20 per hour for all connected time; Preply and italki allow teachers to set their own rates, with experienced tutors earning $15–$35+ per hour. Online teaching suits people building a flexible secondary income, parents with care responsibilities, or career changers testing the TEFL waters before committing to international relocation.
Entry requirements and routes into TEFL
Route 1: 120-hour TEFL certificate (standard entry)
The 120-hour TEFL or TESOL certificate is the universally recognised minimum standard for entry-level teaching positions. The 120-hour figure refers to the total study time required, which can be completed in as little as four weeks on an intensive course or over twelve weeks part-time. Most reputable 120-hour courses cover: language analysis and grammar; lesson planning and methodology; teaching different skills (reading, writing, listening, speaking); classroom management; assessment; and teaching practice. The teaching practice component – typically six hours of observed practice with real learners – is an important differentiator between higher-quality certificates and cheaper online-only options.
Route 2: 120-hour online TEFL certificate (the learndirect Pathways route)
Online TEFL certificates covering the full 120-hour curriculum are widely accepted by language schools and online platforms. learndirect Pathways offers 120-hour TEFL certification online, allowing you to study at your own pace with tutor support and complete the course in four to twelve weeks depending on your schedule. The qualification is accepted by employers internationally and is an ideal choice for people who want to prepare for TEFL while still working in their current role.
Why this matters: The TEFL industry is largely unregulated in terms of mandatory qualification requirements, but 120 hours has become the de facto standard that serious employers and online platforms use to filter applicants. Certificates below this threshold may not be accepted by reputable employers. A 120-hour TEFL certificate with a teaching practice component is the safest investment for anyone planning to teach professionally.
Do I need a degree for TEFL?
A degree is not required for many online teaching platforms and some in-country positions, but it significantly expands your options. Countries with work-permit visa requirements – including South Korea, Japan, China, Saudi Arabia, and the UAE – typically require a degree as a condition of the work visa, regardless of TEFL qualification. European positions vary by employer and country. Online platforms that do not require a degree include Cambly and italki (where teachers are self-employed tutors). Platforms that require a degree include EF and most organised recruitment programmes.
If you do not hold a degree and want to maximise your TEFL options, the most practical step is to pursue a degree alongside or after your TEFL certificate, or to focus on online teaching platforms that do not impose the degree requirement while you build experience and consider your longer-term path.
How the qualification works
A 120-hour TEFL course is structured around theoretical modules and practical application. Online delivery via learndirect Pathways includes: video-based lessons explaining language teaching principles; written assignments testing your understanding of grammar, lesson planning, and methodology; reading materials covering research-backed teaching approaches; and feedback from qualified TEFL tutors on your written work. The teaching practice element – which may be completed with real learners in a supervised session arranged by the provider, or via a recorded practice lesson reviewed by a tutor – brings the theory to life and prepares you for the realities of standing in front of a class.
On completion, you receive a TEFL certificate in your name from an accredited provider. Reputable certificate providers include learndirect (OFQUAL-regulated where applicable), i-to-i, CELTA (Cambridge), and DELTA (Cambridge). The Cambridge CELTA is widely regarded as the premium qualification, particularly for positions at British Council-affiliated schools – though it is significantly more expensive and intensive than a standard 120-hour certificate and is typically undertaken in person over four weeks.
How long does it take?
- 120-hour TEFL certificate (intensive, full-time): 4 weeks
- 120-hour TEFL certificate (part-time, online): 6–12 weeks
- Cambridge CELTA (intensive, in-person): 4 weeks full-time
- Degree (for visa-restricted destinations): 3 years full-time or 4–6 years part-time online
Expected earnings
TEFL earnings vary dramatically by location and employment model. The table below reflects 2025 market rates across the main contexts.
| Context / Location | Typical Monthly Earnings | Notes |
|---|---|---|
| Online platforms (Cambly, italki) | $10 – $25/hour | Flexible, variable hours, set own schedule |
| Preply / Wyzant (self-set rate) | $15 – $40/hour | Experienced tutors earn more |
| Spain (private language school) | £800 – £1,100/month | Lower cost of living offset |
| South Korea (EPIK / GEPIK) | £1,150 – £1,550/month + benefits | Flights, accommodation, health insurance included |
| Vietnam / Thailand | £1,000 – £1,500/month | High relative purchasing power locally |
| UAE / Saudi Arabia | £2,000 – £4,000/month tax-free | Often includes accommodation and flights |
| UK (private EFL school) | £22,000 – £28,000/year | Seasonal and competitive market |
Tax-free packages in the Gulf are particularly attractive when viewed in terms of take-home income – a UAE teacher earning £2,500/month tax-free has significantly more disposable income than a UK-based professional earning a nominally higher gross salary. Online teaching income is typically taxable in the UK for UK-resident teachers and must be declared to HMRC.
Your step-by-step pathway
- Confirm your English language proficiency
TEFL teaching requires a near-native or native level of English competence. If English is your first language, this is clearly not a barrier. If English is your second language but you are highly proficient, check the specific requirements of your target employers – many platforms and schools accept non-native speakers who can demonstrate C1 or C2 proficiency (IELTS 7.5+ or equivalent). Some countries and employers specifically require native English speakers. - Decide on your target market
Before choosing a course, decide whether your goal is online teaching, teaching abroad in a specific region, or teaching in the UK. This determines whether you need a degree in addition to your TEFL certificate, what level of qualification depth is required, and how quickly you can get started. Online teaching has the lowest barriers to entry and the fastest time to first income. Teaching abroad in Asia or the Middle East typically requires a degree and more thorough preparation. - Enrol on a 120-hour TEFL course
Choose a reputable 120-hour TEFL certificate programme with a clear curriculum, qualified tutors, and a teaching practice component. learndirect Pathways offers 120-hour TEFL certification online at a flexible monthly subscription, allowing you to study around existing work and complete the qualification in four to twelve weeks. Ensure the certificate is from a recognised provider and clearly states the 120-hour completion in the certification documentation. - Complete the course and receive your certificate
Work through the modules systematically, engage with tutor feedback on your assignments, and take the teaching practice seriously – this is the component that most directly prepares you for the classroom. Once you pass all components, your certificate is issued and you can begin applying for positions immediately. - Prepare your application materials
Create a professional CV tailored for TEFL applications. Include your TEFL certificate details, any relevant experience working with children or in education, language skills, and a clear statement of your teaching goals. For international positions, research visa requirements and any mandatory background checks (a DBS certificate is typically required for positions involving children). Many employers in South Korea, Japan, and China require an apostille-certified degree certificate and a criminal record check from your home country. - Apply for positions or set up your online profile
For online teaching, create profiles on Preply, italki, or Cambly and complete any platform certification they require. Film a professional-quality introduction video – a warm, clear, engaging video is the single most important factor in attracting students on self-directed platforms. For international positions, use TEFL job boards (Dave's ESL Cafe, ESLcafe, Teach Away, or the British Council's TeachEnglish site) to find openings. Apply widely and be responsive – good positions fill quickly. - Begin teaching and continue developing professionally
Your first lessons will be the steepest part of the learning curve. Reflect honestly after each session on what worked and what did not, seek feedback from students and peers, and continue building your lesson planning and classroom management skills. Consider additional qualifications – such as the Cambridge DELTA or specialist EAP (English for Academic Purposes) or Business English certificates – once you have a few years of experience and want to progress to more senior or specialist roles.

Frequently Asked Questions
What is the difference between TEFL and TESOL?
TEFL (Teaching English as a Foreign Language) and TESOL (Teaching English to Speakers of Other Languages) refer to the same type of teaching and are used interchangeably in most contexts. TEFL tends to be used more commonly for overseas teaching positions, while TESOL is sometimes preferred by North American providers and in academic contexts. Both terms describe English language teaching to non-native speakers, and a TEFL or TESOL certificate is accepted for the same range of positions worldwide. There is no meaningful difference in the value of a TEFL certificate vs a TESOL certificate from a reputable provider.
Do I need to speak another language to teach TEFL?
No. TEFL methodology is specifically designed around teaching English through English – so-called “immersive” teaching – without requiring the teacher to share the learner's first language. In fact, many experienced TEFL teachers actively avoid using the learner's first language even when they can, as immersive English teaching is generally more effective for language acquisition. A second language is helpful for navigating daily life if you are living abroad, but it is not a professional requirement for the classroom.
How much can I earn teaching English online?
Online earnings depend significantly on the platform and your experience level. Platforms with fixed rates such as Cambly pay around $10.20 per hour for connected time. Self-directed platforms such as Preply and italki allow teachers to set their own rates – new teachers typically start at $10–$15 per hour, building to $20–$40+ per hour as they accumulate reviews and repeat students. Consistent online teachers with an established student base and strong reviews can earn £1,000–£2,000+ per month working part-time hours.
Is a degree required to teach English abroad?
It depends on the destination. Countries including South Korea, Japan, China, Saudi Arabia, and the UAE typically require a degree as a condition of the work visa, in addition to a TEFL certificate. European positions vary by country and employer. Online platforms such as Cambly and italki do not require a degree. If you do not have a degree and want to teach in visa-restricted countries, an online degree programme from learndirect Pathways is a practical way to qualify while continuing to teach online in the short term.
How long does a 120-hour TEFL course take to complete?
A 120-hour TEFL course can be completed in as little as four weeks on an intensive schedule, or over six to twelve weeks on a part-time basis studying evenings and weekends. The 120-hour figure refers to the total study time, not the calendar duration – so if you can dedicate four to five hours per day, four weeks is realistic. Working adults studying alongside full-time employment typically take eight to twelve weeks. learndirect Pathways allows you to work at your own pace within a flexible subscription.
What is the CELTA and is it better than a standard TEFL certificate?
The Cambridge CELTA (Certificate in Teaching English to Speakers of Other Languages) is widely regarded as the most prestigious entry-level TEFL qualification, particularly for positions at British Council-affiliated schools and prestigious language institutes worldwide. It is significantly more rigorous and expensive than a standard 120-hour TEFL certificate, requiring intensive in-person study over four weeks with substantial observed teaching practice. For many positions, particularly online platforms, private language schools in Asia, and standard international school positions, a 120-hour TEFL certificate is entirely sufficient. The CELTA is recommended if you specifically want to teach at British Council schools or are targeting the most competitive positions in major European cities.
