  • Summative Task (Thesis)

Modules 1 to 11 will each require in the region of 21 hours of study time. The summative task requires a research-based thesis that usually takes in the region of 20 hours to complete. Therefore, you should allocate around 250 hours of study time to complete the whole course.

Diploma Course Aims

Our advanced diploma course includes a wide variety of content, ranging from educational theories to teaching material design, which is specifically aimed at providing you with a clearer understanding of the role of the teacher in an English language classroom.

As you work your way through the course modules you should find that you gradually develop a wide range of transferable skills that will be of use both inside and outside of the classroom, especially skills such as essay writing and research related techniques.

Diploma Course Assessment

The diploma course includes a multiple choice test at the end of each module. Once you have completed the test for each individual module your answers will be automatically marked and the results shown in a graph format. Following completion of the eleven course modules, you will then need to submit a research project as outlined in the summative task.

Upon successful completion of all the module tests and the end of course thesis, you will graduate and receive your online TEFL/TESOL Diploma certificate.
