Is OnTESOL Right for You?

Choosing the right TESOL/TEFL course is an important decision. With so many programs available, it’s essential to select one that provides both high academic standards and practical teaching skills.

OnTESOL is designed for those who want to teach English professionally—whether abroad, online, or in Canada and USA.

OnTESOL vs. Foundational TEFL Courses

We specialize in professional-level training because most TESOL/TEFL courses fall short. Many online courses only provide foundational knowledge through basic tests and essays, leaving teachers unprepared.

OnTESOL Foundational
✅ Professional-level, globally recognized certification ❌ Foundational-level, often unrecognized in top destinations
✅ Practical training with real lesson planning assignments ❌ Basic essays and multiple-choice tests
✅ Prepares for long-term, international career success ❌ Limited to entry-level gap-year experiences
✅ Accepted in Canada, the U.S., and abroad ❌ Often require additional training to meet employer standards
✅ Designed for aspiring and experienced teachers ❌ Geared toward beginners with minimal career focus

30% of our students came to OnTESOL after realizing their first TESOL course wasn’t enough!

How OnTESOL Stands Out

Unlike many introductory TEFL courses that focus on theory alone, OnTESOL emphasizes real teaching practice through structured lesson planning assignments, live instruction, and interactive components.

What you’ll gain:

  • Advanced TESOL Training : Covering grammar, phonology, and teaching methodologies.
  • Hands-On Learning: Practice creating real lesson plans with expert feedback.
  • Flexible & Practical Approach: Self-paced learning with structured support.
  • Internationally Recognized Certification: Qualify for a wide range of teaching jobs.

At OnTESOL, we hire teacher trainers with more than 10 years of experience in the ESL classroom and more than 5 years of experience in CELTA, Trinity CertTESOL, or TESL Canada approved courses. Some of our tutors bring more than 30 years of industry expertise! All of our tutors are TESL Canada recognized, ensuring you receive professional guidance from highly qualified and experienced educators.

What OnTESOL Trainees Are Looking For

Our students have one thing in common: they want advanced, accredited TESOL training that is affordable, flexible, and globally recognized.

With OnTESOL, you get:

  • Affordable & Advanced – Get high-quality training at a competitive price.
