Teaching English abroad or online remains an attractive career option for people who want greater flexibility, international experience, or the opportunity to work while travelling. For most aspiring English teachers, the first step is earning a recognised TEFL certification.
But how do you become TEFL certified? Do you need a degree? Is a 120-hour TEFL course enough? And can you complete your certification entirely online?
This guide explains what TEFL certification is, how online TEFL courses work, and what to consider when choosing a course in 2026.
What Is TEFL Certification?
TEFL stands for Teaching English as a Foreign Language. A TEFL certification provides training for people who want to teach English to learners whose first language is not English.
TEFL courses typically cover areas such as:
- English teaching methodology
- Grammar and language awareness
- Lesson planning
- Classroom management
- Teaching vocabulary and pronunciation
- Teaching reading, writing, listening and speaking
- Assessing students
- Teaching different learner groups
TEFL qualifications are commonly used by people seeking English teaching positions abroad or online.
How Do You Get TEFL Certified Online?
Getting TEFL certified online is relatively straightforward.
1. Choose an Appropriate TEFL Course
Start by choosing a course that matches your career goals. Course length is particularly important because employers may specify a minimum number of training hours.
A 120-hour TEFL course is commonly chosen by people preparing to apply for English teaching positions, while longer courses can provide additional training and a more comprehensive qualification.
TEFLEN, for example, offers both an Advanced 120-Hour TEFL Course and a Master 150-Hour TEFL Course, along with specialist courses for teachers interested in areas such as Business English, teaching young learners and online teaching.
2. Enrol and Study Online
With an online TEFL course, there is normally no requirement to attend a physical classroom.
TEFLEN courses are delivered online, allowing students to study from home or while travelling. Students can work through their course according to their own schedule rather than attending fixed classes.
This flexibility can be particularly useful for students who are already working or studying.
3. Complete the Course Assessments
TEFL assessments are designed to ensure that students understand the principles and practical aspects of teaching English.
Depending on the course, assessments may include quizzes, written work and practical exercises such as lesson planning.
4. Receive Your TEFL Certificate
After successfully completing the required course components, you receive your TEFL certification.
Your certificate can then be included with applications for English teaching positions and presented to prospective employers where required.
Do You Need a Degree to Get TEFL Certified?
Generally, you do not need a university degree simply to complete a TEFL course.
This is an important distinction because TEFL course requirements and employment or visa requirements are not necessarily the same thing.
A person may be eligible to complete a TEFL qualification without holding a degree, but an employer or country’s work visa regulations may separately require a bachelor’s degree.
If you have a particular country in mind, check its current visa requirements before making employment or relocation plans.
Is a 120-Hour TEFL Course Enough?
A 120-hour TEFL certification is one of the most commonly recognised benchmarks in the TEFL industry.
For someone who is serious about pursuing English teaching opportunities, a 120-hour course is generally a stronger choice than a very short introductory TEFL course.
However, more training can be beneficial.
A 150-hour TEFL course provides additional study and may be particularly attractive to students who are new to teaching and want more comprehensive preparation before entering a classroom.
At TEFLEN, students can choose between options including the Advanced 120-Hour TEFL Course and Master 150-Hour TEFL Course depending on their objectives.
120-Hour vs 150-Hour TEFL: Which Should You Choose?
The right choice depends largely on your career plans.
A 120-hour TEFL course can be suitable if you want a comprehensive qualification that meets the commonly requested 120-hour benchmark.
A 150-hour TEFL course may be preferable if you want more extensive training, are completely new to teaching, or simply want to strengthen your preparation before applying for teaching positions.
Rather than choosing a course solely because it is cheaper or faster, consider what you actually want to do after certification.
Can You Teach English Abroad With a TEFL Certificate?
A TEFL certificate can help you qualify for English teaching opportunities in many countries, but there is no single worldwide employment standard.
Requirements vary according to:
- Country
- Visa regulations
- Employer
- Type of school
- Teaching position
- Applicant’s educational background
- English proficiency requirements
Countries across Asia, Europe, Latin America, the Middle East and other regions have English-language teaching markets, but their requirements can differ considerably.
For example, someone interested in teaching English in China should investigate current work permit and employer requirements before applying. A TEFL certificate may form part of the required qualifications, but additional requirements can apply.
Can You Teach English Online With TEFL Certification?
Yes. Online English teaching has created another career path for TEFL-certified teachers.
Teachers may work with established online language schools, educational companies or private students.
Online teaching requires many of the same fundamental skills as classroom teaching, but teachers must also learn how to keep students engaged through video lessons, use digital teaching resources effectively and structure lessons for a virtual environment.
A specialist Teaching English Online course can therefore be useful for teachers planning to focus primarily on remote teaching.
What Jobs Can You Get After TEFL Certification?
TEFL certification isn’t limited to one type of job.
Depending on your qualifications, experience and location, potential opportunities can include:
- English language teacher
- Online English tutor
- Private English tutor
- Business English teacher
- Young learner teacher
- English conversation instructor
- Language school teacher
- Corporate English trainer
Some teachers also combine different types of workâfor example, teaching at a language school while tutoring private students online.
How Long Does It Take to Get TEFL Certified?
The time required depends on the number of course hours and how much time you dedicate to studying each week.
One advantage of self-paced online TEFL training is that you don’t necessarily have to reorganise your existing work or study schedule around fixed classroom sessions.
However, completing a TEFL course shouldn’t simply be a race to obtain a certificate. The purpose of the training is to develop practical knowledge that you can use when you begin teaching.
What Should You Look for in an Online TEFL Course?
Before enrolling, consider more than the headline price.
Look at:
- Total course hours
- Course curriculum
- Accreditation
- Assessment structure
- Tutor or trainer support
- Time allowed for completion
- Certificate verification
- Specialist training options
- Reputation and history of the course provider
TEFLEN has provided online TEFL/TESOL training since 2013 and offers internationally accredited courses with online study and trainer support.
Frequently Asked Questions About TEFL Certification
Can I get TEFL certified completely online?
Yes. Online TEFL courses allow students to complete their training remotely without attending a physical training centre. Always check the particular requirements of employers or countries where you intend to work.
Is 120 hours enough for TEFL?
A 120-hour TEFL course is a commonly recognised level of training and is frequently chosen by people intending to pursue English teaching opportunities.
Is a 150-hour TEFL course better than a 120-hour course?
A 150-hour course provides additional training hours. It may be a good choice for someone who wants more comprehensive preparation, particularly if they have little or no previous teaching experience.
Do I need teaching experience before taking a TEFL course?
No. TEFL courses are commonly taken by people who have never taught professionally before.
Do I need a bachelor’s degree for TEFL?
A degree is not necessarily required to study for a TEFL qualification. However, individual employers and countries may require a bachelor’s degree for particular jobs or work visas.
Can non-native English speakers take a TEFL course?
Yes. Being a non-native English speaker does not automatically prevent someone from studying TEFL or pursuing English teaching opportunities. However, individual employers may have their own English proficiency and recruitment requirements.
Can I use TEFL certification to teach in China?
TEFL certification can be relevant to English teaching positions in China, but applicants should separately check current employer and Chinese work permit requirements. Requirements can change and may depend on the position and applicant.
Does a TEFL certificate expire?
TEFL qualifications themselves generally do not have a conventional expiry date, although employers may have their own requirements concerning qualifications, recent experience or additional training.
Start Your TEFL Journey
A TEFL qualification can open the door to teaching opportunities around the world and online. The important thing is to choose a course that provides sufficient training for your intended career path rather than simply looking for the quickest certificate available.
TEFLEN offers several online training options, including the Advanced 120-Hour TEFL Course and the more comprehensive Master 150-Hour TEFL Course, allowing students to choose a qualification that suits their goals.
Whether you want to teach English abroad, work online, teach young learners or eventually specialise in Business English, developing a strong foundation in English-language teaching is an important first step.
