In 2004–05, approximately 15.29 lakh (1.529 million) students were enrolled in primary schools, 8.22 lakh (0.822 million) in middle schools and 6.69 lakh (0.669 million) in secondary schools across Delhi.

After completing the ten-year secondary phase of their education under the 10+2+3/4 plan, students typically spend the next two years either in junior colleges or in schools with senior secondary facilities, during which their studies become more focused. They select a stream of study—liberal arts, commerce, science, or, less commonly, vocational. Upon completion, those who choose to continue, either study for a three-year undergraduate degree at a college, or a professional degree in law, engineering, or medicine.
