The D & H College TESOL 300 Diploma program, approved by PTIB, provides students with a thorough understanding of ESL teaching methods that assists in the development of practical teaching abilities. This program teaches students not only how to teach but also the reasoning and theory behind both the modern, accepted classroom practices of English as a Second Language teaching and learner language acquisition. With a 50-hour supervised practicum component, including 20 supervised practice teaching hours of ESL class and 30 hours of guided observation of some experienced ESL teachers, trainees gain genuine insight into the classroom experience of both teachers and learners.
