What is ESL?
ESL is an acronym for “English as a Second Language.” It refers to programmes or courses designed to help non-native speakers learn English. These programmes are generally targeted at individuals residing in an English-speaking country who need to enhance their personal, academic, or professional language skills.
What is EFL?
EFL is an acronym for “English as a Foreign Language.” It refers to learning English by non-native speakers in countries where English is not the primary language. EFL programmes focus on teaching English to students who may use it for international communication, travel, or future education and work opportunities.
What are EFL, ESL, TEFL, TESL and TESOL and how are they different?
For several reasons, understanding why EFL and ESL teaching styles are different is essential for an English teacher.
In addition, understanding the difference between TEFL, TESL, and TESOL training courses is also essential because you want to get the proper training and not find out you wasted money after taking a course.

The Differences Between TEFL, TESL, and TESOL
TEFL – Only Covers EFL Skills
TEFL is an acronym for “Teaching English as a Foreign Language.” It refers to teaching English to non-native speakers in countries where English is not the first language. TEFL is used in various educational settings, and understanding its application is crucial for effective teaching.
TEFL is commonly used in public schools, private language schools, and international schools where English is taught as part of the curriculum.
TEFL certification opens opportunities to teach English worldwide, allowing teachers to work in diverse cultural settings and experience different educational systems.
Overall, TEFL is a dynamic and rewarding field that is crucial to spreading English language proficiency worldwide. It allows teachers to significantly impact their students’ lives while providing opportunities for personal and professional growth.
TESL – Only Covers ESL Skills
TESL is an acronym for “Teaching English as a Second Language.” It refers to teaching non-native English speakers who live in English-speaking countries. The primary goal of TESL is to help learners acquire the language skills necessary to communicate effectively and integrate into their new environment, whether for work, education, or daily life.
TESL is often used in environments where learners are immersed in English outside the classroom. This immersion allows teachers to use real-life contexts to reinforce language learning.
TESL focuses on developing practical communication skills, such as speaking and listening, to help students navigate everyday situations. Lessons might include vocabulary and phrases relevant to shopping, transportation, or healthcare.
Primarily, TESL empowers learners to function independently in English-speaking environments, enhancing their personal and professional opportunities.
TESOL – Covers EFL and ESL Skills – The Recommended Choice
TESOL is an acronym for “Teaching English to Speakers of Other Languages.” It is a broad field encompassing ESL and EFL. TESOL is a term often used to describe teaching English to non-native speakers and the certification programmes that prepare individuals for this career.
TESOL is applicable in a wide range of settings, including public and private schools, universities, language institutes, and adult education centres, both in English-speaking and non-English-speaking countries.
TESOL is similar to TEFL but often more comprehensive, covering both ESL and EFL contexts. In some regions, it may be used interchangeably with TESL (Teaching English as a Second Language), though TESL typically refers specifically to teaching in English-speaking countries.
TESOL-certified teachers can work in various roles, such as classroom teachers, curriculum designers, language program coordinators, and teacher trainers.
TESOL certification can open doors to teaching positions worldwide, as English is in high demand for global communication, education, and business.
In summary, TESOL is a combination of TEFL and TESL. It is the most versatile and comprehensive teacher training available, letting you teach English to non-native speakers anywhere in the world. TESOL plays a vital role in addressing the global demand for English language education, helping you achieve your goals and enhancing your opportunities.
The Differences Between EFL and ESL
Let us dive into the exciting world of ESL and EFL teaching and unravel their unique contexts. In ESL settings, students are immersed in an English-speaking environment, offering endless opportunities for real-world interactions. This environment fosters practical language use as learners integrate English into their daily lives. In contrast, EFL students in non-English-speaking countries rely on structured classroom activities to mimic language exposure, as their practice opportunities outside class are limited.
Motivation plays a vital role in these different environments. ESL students often learn English out of necessity, such as for work or education in English-speaking countries, which drives the urgency and shapes lesson planning. Meanwhile, EFL students generally study English for future travel or educational purposes, influencing their motivation and the structure of their lessons. Teaching methods reflect these differences: ESL teachers can leverage authentic materials that mirror daily life, while EFL teachers use textbooks and audio aids to replicate real-world usage. Moreover, with their diverse cultural backgrounds, ESL classrooms demand flexible management strategies, whereas EFL classrooms benefit from tailored approaches due to their shared language and culture.

Which Certification Course Is Right for You?
So, you are ready to teach English abroad, but which certification course should you choose? Your decision might hinge on your career aspirations, budget, desire to travel, and the country you’re passionate about.
Here’s the key – what matters most is that your certification comes from a highly accredited institution.
Here are the vital components to consider when selecting your course. The British Council publishes these requirements, which are usually highlighted by most generic TEFL and TESOL courses. Look at the first paragraph on page 2 of this British Council publication https://www.britishcouncil.org/sites/default/files/guidance_for_providers_on_assessing_teaching_and_learning_feb_18.pdf.
The globally accepted British Council TEFL/TESOL course requirements
Many generic TEFL/TESOL certification courses quote these requirements and claim to meet them but many fall short.
To guarantee you earn a reputable qualification, make sure your chosen course includes:
- be externally validated* by a reputable examination body (usually a university or recognised examination board) and/or accredited by a national accrediting body such as Ofqual in England;
- contain at least six hours’ supervised teaching practice (i.e. teaching practice where a qualified and standardised assessor observes the trainee teacher teaching real TEFL students and gives feedback to the trainee on their performance);
- contain at least 100 hours of ELT/TESOL input.
* The Scheme requires external validation (accreditation) to ensure consistency and rigour of standards. Where a certificate course leads to an international award, there needs to be a system to ensure consistent standards between courses within a centre and between course providers. Reputable examination bodies (amongst other things) set standards for the syllabus and course content, for the appointment of course trainers with respect to their qualifications and experience, for the training of the assessors of both written and practical work. They also train external moderators of the course who visit each course and moderate the awards. The examination board also provides an external complaints procedure. The procedures provide a level of externality that can show trainees that a certificate has the same worth regardless of where or when it was taken.
Why do many generic TEFL and TESOL courses fail to meet the globally accepted course requirements?
Most generic TEFL and TESOL courses fail to meet the requirements for points 1. and 2. mentioned in the previous section titled “The globally accepted British Council TEFL/TESOL course requirements“.

- Update Materials: Regular course materials updates to align with current standards and best practices.
- Qualified Trainers: The examination body has independently vetted all course trainers against the required qualifications and experience criteria.
- Record Keeping: Records of trainer qualifications and experience are kept for compliance audits.
- External Moderation: Independent, external moderators visit each course to moderate it, interview all course attendees, and perform quality control checks against the examination body’s standards.
- Complaints Procedure: Operate and communicate an independent external complaints procedure.
- Documentation: Keep comprehensive records of accreditation, assessment, moderation, complaints processes and associated documents.
Point 2. failures
Many generic TEFL and TESOL courses do not have teaching practice in which a qualified and standardised assessor observes the trainee teacher teaching real English language learners and gives feedback to the trainee on their performance. The examination board must approve the qualified and standardised assessor as a competent assessor. Most generic TEFL and TESOL courses do not operate this way.actice.
