 TEFL TESOL Guide to Teaching English Abroad Specialized Advanced Courses A range of more specialized or advanced qualifications is available for teachers that already have or are studying for TEFL certification. Most popular and specialized courses are Certifications in Teaching Business English and Specialist Certification in Teaching English to Young Learners. Both of these are usually 50-hour online courses and therefore no classroom attendance is required. These are useful qualifications for anyone who wishes to specialize in either of these areas as well as providing additional useful qualifications to a teacher that has just completed a TEFL TESOL course. The most advanced TEFL TESOL qualification is the Diploma in TEFL. This course is a very high-level, 250-hour course that builds upon knowledge gained from the TEFL Certificate course. The TEFL Diploma course again is a 100% online course without any requirement for classroom attendance, but you must already possess an internationally recognized TEFL certificate in order to be accepted onto a TEFL Diploma course. Beware of courses claiming to be diploma courses but which offer less than 200 hours of study. These qualifications are not true diploma courses and most employers will not recognize them as such.
