The Certificate in Teaching English to Speakers of Other Languages (CertTESOL) is a recommended qualification for teaching English in New Zealand and overseas. No prior teaching experience is necessary for this course: CertTESOL provides trainees with practical experience of language teaching with ample opportunities to plan, teach and evaluate lessons. Trainees attain a high level of practical competence and understanding of language teaching required for employment in this field.

AIS CertTESOL graduates who want to stay and work in New Zealand have the option to take English teaching opportunities with various local English language providers or within the AIS English Language Centre. AIS offer career advice and guidance.
