Why are TEFL teachers important?

January 30, 2026

TEFL teachers are important because they provide a vital in-demand skill – speaking English – that is valued worldwide.

As a TEFL teacher, you will be in high demand from language schools because this is an essential skill for students globally in both developing and prosperous countries.

English is a global language

English is the most widely spoken language in the world. 

It bridges different cultures and religions and allows global communication and understanding.

When you are TEFL qualified and teaching English abroad, you will be part of this process.

Speaking English is a key life skill

The opportunity to acquire English as a foreign language could empower your students to have more successful and lucrative careers.

A good standard of English language is essential for students planning to study abroad in an English-speaking country or to progress in international business.

The popularity of learning English as a foreign language

English is the most widely spoken second language in the world for all the above reasons, ensuring a large number of teaching positions for TEFL teachers.

Why a great TEFL teacher is so important

The learning process can be difficult, particularly if a student is learning English in their home country without constant exposure to the language.

As a great English teacher abroad, your knowledge, skills, enthusiasm and empathy will transcend language barriers, creating a learning environment where students can learn confidence and fluency.

How does a TEFL certificate prepare you for this role?

Becoming TEFL certified is essential for two reasons:

Training you to fulfil the role of TEFL teacher

A good TEFL course will give you the knowledge and skills to be a great TEFL teacher and will include modules on lesson planning, English grammar, and teaching methods.

The requirements of language schools in other countries

Most employers require TEFL teachers to have high-level qualifications, such as our accredited Level 5 TEFL Diploma.

Other skills the best TEFL teachers possess

The best TEFL teachers also possess good communication skills and an ability to use body language effectively, especially when working in a new country where you need to transcend language barriers to teach.

Teaching English abroad as a career

By achieving TEFL certification, you will be opening doors to a new adventure working in different countries all over the world.

Many of our students love the flexibility of freelance work abroad. 

However, many TESOL teachers work in language schools because they enjoy job security, opportunities for professional development, and further career opportunities.
