Online TEFLs are usually regulated by governing bodies, such as Qualifi in the UK and AQC (from the DEAC) in the United States.
A no level TEFL course does not give a certificate recognised by an awarding body.
A level 3 course is 120 hours long and is considered the equivalent of a high school diploma.
[1] The TEFL Online certificate was designed by foreign language teachers in the Ontario Institute for Studies in Education (OISE) at the University of Toronto.
The certificate is provided in partnership with Teach Away, an international teacher recruitment company.
