With the desire to make English the 2nd language in Vietnam and bring real value to the achievement of success and happiness in life, IRIS aims to become one of the leading educational groups in Middle Central Highlands. At IRIS, Power English classes are highly appreciated. This is the subtle combination between two learning methods today: Effortless English and Crazy English. However, IRIS staff have researched and selected the appropriate elements in learning and acquiring knowledge towards the Central Vietnam in particular and the whole country. Along with NLP (Neuro-linguistic programming) IRIS also helps students explore the underlying potentials of each individual and apply them to learn English in the most effective way.
