English for Integrated Studies (EIS) is a new model of bilingual education first introduced in the Kingdom of Thailand.
In the EIS project Thai teachers instruct their classes (Science, Mathematics, Computer and English) in English language using English textbooks. The low amounts of tuition fees paid by the students are used to train the Thai teachers to use English as a medium of instruction. Then Teachers improve their skills by on-the-job-training and students improve their English language skills in the new created English environment.
