Frequently Asked Questions

Are Online TEFL Courses accepted as opposed to in-house?
There is a lot that can be said about this issue but we will try to address it as brief as we possibly can. First, we need to ask the following questions:
  • Did living in caves prove to be better shelter than manmade homes?
  • Were horse driven buggies better than cars?
  • Was communicating via Telegraph better than the Telephone?
  • Is corresponding via letters/postal mail better than email?
  • Is getting the news via newspapers better than through Television or the Internet?
  • Is searching for information via Encyclopedias better than using the Internet?
Human advancement from their old approaches to new versions have always been opposed by those afraid of change and technology based improvements. There are rumors that schools worldwide do not recognize TEFL type online degrees.
This is almost a completely insignificant proclamation, because presently they only account for less than 1% of all educational establishments worldwide and this is decreasing every day. Online education in general, today is the norm as opposed to the exception. Degrees of all variance and levels are being obtained online, including ones even of higher education caliber and are widely accepted in this global world.
All companies that offer in-house courses also offer online, therefore this debate is moot since they themselves recognize the need for it.
Well-structured TEFL online courses:
  • are by far cheaper
  • do not require traveling
  • are convenient and can be taken at the student’s own pace
  • if the syllabus and site is user-friendly as well as technologically advanced (such as live timed exams), they thus can be completely comparable to in-house.
What is the difference between TEFL, TESOL, CELTA etc. courses?
There are no major differences. They are just referring to a slightly different meaning and thus a different acronym. However, they all refer to the same original acronym and course; TEFL “Teach English as a Foreign Language” CELTA is the original and at one time was the Cadillac of all courses but as teaching abroad has changed, the curriculum for CELTA has not and is now outdated but yet still overpriced..
Do I really need TEFL in order to teach abroad?
Yes. In recent years this has become the biggest change in the market as now almost all schools across the board require TEFL certification and that even includes teachers who have a teaching certification in their country of birth because TEFL is a specialization. It is required for both native and non-native speakers. Not only do the schools require it, various countries request this from the schools for VISA and immigration purposes. Therefore, TEFL degrees have become mandatory and this includes even if you have other highly regarded credentials. Additionally many schools will not even consider candidates for their vacant positions who do not have such TEFL type degrees.
Yes. Due to our excellent reputation amongst International Employers, Partners, Educational Agencies and Associations for the past 17 years, SeriousTEFL Diploma is recognized by thousands of employers worldwide.
