International TEFL Academy and INTESOL Worldwide

[Benedick]

Can anyone give advice/feedback/opinion on the organisation International TEFL Academy? I'm wondering whether to train with them.

Their accreditation is by INTESOL Worldwide (at least online, if not onsite). Apparently this has attained NQF Levels 4 and 5 (not sure why it states both levels) by the NCFE (a reliable source?). Their employee on the phone told me this was equivalent to the CELTA and TrinityCert NQF levels. Is this true and does that make the course equivalent to these highly respected ones?

Thanks,
Ben
