The Delta Exam is designed for experienced English language teachers to further their careers through three modules: 1) Understanding language methodology and resources, 2) Developing professional practice through lesson planning and teaching, and 3) Extending practice in a specialist area or English language teaching management. Module 1 is assessed through written exams, Module 2 through a teaching portfolio, and Module 3 through an extended written assignment focused on a specialist topic or management area. Successful completion of all three modules results in a Delta qualification certificate.
