Why TEFL Qualifications are Key

Monday 16th October 2017

It’s no secret that the English teaching industry is one of the fastest growing internationally. Every year, countless, freshly-qualified teachers search for jobs, hoping to carve themselves a slice of the proverbial language cake. New English academies spring up every day, and with them arise more and more TEFL qualifications – often companies offering ‘internationally recognised’ certificates, verified by mysterious third-party bodies.

English teaching hopefuls often find themselves lost in the minefield of industry abbreviations: TEFL, TESOL, CELTA, Delta, ESL and ELT. It’s hard to know which one will actually get you trained, qualified and ready to teach – and, more importantly, which one employers are after.

Why TEFLwork?

TEFLwork cuts through the white noise of English teaching qualifications – our advertisers are only looking for the best, most widely recognised certificates; the CELTA, Delta and Trinity TESOL.

A quick search of any other job board will uncover a range of adverts looking for anyone with a native tongue and a brain – these are exactly the kinds of employers you want to avoid. Our advertisers put qualifications and experience above all-else, and, except for in cases when legislatively required, do not employ candidates based on age, ethnicity, gender, nationality or first language.

When you apply for jobs on TEFL Work, you’re applying for jobs you can trust – businesses that pay a fair wage, employ their teachers legally, and value education and know-how.

How can I get qualified?


It’s the buzz-acronym of the English teaching world; the Certificate of English Language Teaching to Adults. Developed and standardised by the world-renowned Cambridge University, CELTA can be studied just about anywhere in the world full-time, part-time or online blended. The only requirements are a near-native level of English and a high school education.

The 120-hour course is made up of theory course work, lesson planning, take home assignments, class and tutor feedback and, most importantly, hours of real-life, in-class teaching experience. Employers prefer candidates who apply with the CELTA certificate in-hand, because they know that they come with a guaranteed skill set, a globally standardised education, and experience in the classroom.

Delta – like its little brother CELTA – is a world-recognised qualification from the University of Cambridge. Its main difference is the letter ‘D’ – for Diploma – making the course tertiary-level, and one of the most highly-regarded in the TEFL world.

After completing a CELTA certificate or equivalent, and a couple of years teaching to a variety of levels, candidates are eligible to study the Delta. The diploma is broken up into three main modules – the first; a written exam, the second; an intensive course and the third; a miniature thesis. The months-long certificate is no walk in the park – and employers know it.

The Delta is a qualification for English teachers looking to advance their careers beyond just the classroom, to directive, administrative and leadership roles.
