You may be asking yourself, is iTTT right for me? Well, there is no better time than now to find out why it’s one of the top-rated TEFL programs available today.

If you are looking for a professional or accredited TEFL or TESOL learning program then you are considering one of the best today. 

iTTT’s programs are broken down into 6 main types:

  • Online Diploma/Course
  • In-Class Course
  • Combined Course
  • Specialized TEFL Course
  • Observed Teaching
  • Teaching English Online

ITTT Online Diploma/Course

The online diploma course allows you to gain job-relevant skills and industry tools in a 120-hour course.  The iTTT online diploma is an interactive easy to learn and provides learners with an affordable way to study.

Although iTTT has a 60-hour course, we don’t recommend it as it is not sufficient time to gain the skills to be an effective English teacher. Typically, 120 hours is the industry standard for TEFL certification and is the course we favor to select.

In-Class Course

iTTT offers a pretty diverse range of course styles due to the fact it has so many different learning programs. Anyone who’d rather be engaged in a classroom, then this option is for you.

In-class courses generally last 4 weeks with lessons set up all around the world. Some of the benefits of classroom lessons are getting teaching practice, foreign language experience, and direct student interaction and exchange.

Combined Course

The combined course gives you the best of both worlds. You can pick up the theory through online lessons. Then, you can put the theory into practice at a training center. Sites are set up across the United States, Europe, and Asia. 

The combined course includes 6+ hours of observed teaching practice (OTP). As you go through your teaching practice, an experienced professional trainer gives you feedback to help improve your teaching skills.

Specialized Course

The specialized courses are a series of concentrated study areas ideal for someone wanting to master a skill. You could decide to take only one course related to that career skill or the series of courses which would cover all aspects of that skill.

For example, you can teach business English, to young learners or teach English online.  It takes about 50 hours of study to complete each course. You also get tutor support, job guidance, and free access to lesson plans.

ITTT Specialized Course

Teach English Online

This course teaches you how to be a better English teacher online.  Teaching English online has seen the most growth in the last several years. Even after the pandemic, educators still expect to see teaching through online English platforms.

Each English learning platform will pair up with potential candidates for you to earn money and teach English online. The biggest perk is how you don’t have to leave the comfort of your own home.  One of the biggest advantages of completing this iTTT close is that it connects you with alumni currently employed by many of the major employers in online teaching.

Observed Training

This course is designed to increase your ability to teach in the classroom.  If you’re a beginner teacher, there is a lot of value for observed teaching. Peer observation instantly makes you more aware of how you teach.

Through observed training, you get an in-depth understanding and share best practices. This course aims at giving you a crash course into the world of TEFL by throwing you into the classroom from the start.

With the pressures I felt teaching daily during this pandemic, I wondered if I had the energy to complete the course. Final thought, it was worth the time I invested. I have used and will continue to incorporate these strategies in my ESL classroom.

The course material is clearly presented. It was a pleasure to work through the course. I knew I would learn some surprising things, but I didn’t know how much I would be inspired and challenged. This course experience left me feeling even more confident than I had been going into it.
