India

English or the official language of an Indian state (e.g., Bangla, Tamil, Hindi, etc.) is used as a language of Instruction in Indian schools. Syllabus and textbooks are designed by a federal organization called National Council of Educational Research and Training (NCERT) primarily in English. Every Indian state enjoys the liberty to modify the syllabus and textbooks initially designed by NCERT in their local languages and as per their local history and geography. State Council of Educational Research and Training (SCERT) is the organization responsible for the state level modifications. Textbooks designed by NCERT hold classroom instructions for the teachers that they are encouraged to follow.  Quizzes, written and oral tests, lab experiments are commonly used for Assessment.
