Secondary education covers children aged 12 to 18. The final two years of secondary is often called Higher Secondary (HS), Senior Secondary, or simply the "+2" stage. The two halves of secondary education are each an important stage for which a pass certificate is needed, and thus are affiliated by central boards of education under HRD ministry, before one can pursue higher education, including college or professional courses.

UGC, NCERT and CBSE directives state qualifying ages for candidates who wish to take board exams. Those at least 15 years old by 30 May for a given academic year are eligible to appear for Secondary board exams, and those 17 by the same date are eligible to appear for Higher Secondary certificate board exams. It further states that upon successful completion of Higher Secondary, one can apply to higher education under UGC control such as Engineering, Medical, and Business Administration.

After passing the Higher Secondary Examination (the Standard 12 examination), students may enroll in general degree programs such as bachelor's degree in arts, commerce or science, or professional degree program such as engineering, law or medicine. India's higher education system is the third largest in the world, after China and the United States. The main governing body at the tertiary level is the University Grants Commission (India), which enforces its standards, advises the government, and helps coordinate between the Centre and the state.
