CELTA为没有经过培训，很少或没有语言老师经验，或者没有获得NEAS（国家ELICOS认可计划）认可的英语教学资格的教师提供资格。CELTA是举世公认的，是在海外和澳大利亚的许多机构任教的先决条件。成功的候选人将获得基于全球英语教学机构“最佳实践”方法论的英语教学领域的专业知识。
CELTA provides a qualification for teachers without previous training, little or no experience as a language teacher, or without a NEAS (National ELICOS Accreditation Scheme) recognised English language teaching qualification. The CELTA is recognised throughout the world and is a pre-requisite to teach in many institutions overseas and in Australia. The CELTA course prepares candidates for real life teaching through: input sessions from Cambridge accredited CELTA trainers, observed teacher practice with real students, and in depth feedback from trainers, written assessments and self-reflection activities.
