The best course for getting a government job in the drawing and painting field is a Bachelor of Fine Arts (BFA) with a specialization in painting or applied arts. This course gives you the required skills and knowledge to work in government schools, art departments, museums, and cultural centers. After completing BFA, you can also pursue B.Ed if you want to become an art teacher in government schools. Some government exams also have roles related to art and design where this background is useful.
