The district is the pivot of higher education in the entire North East India. Right from the British India period the district has been a center for learning. The Assam Medical College was established by a personal grant from Dr. John Berry White after he retired as the civil surgeon of Lakhimpur district. The medical school, "John Berry White Medical School" was set up in 1900 at Dibrugarh, and thus this premier institute started its history, and marked a new era in education.[11] Assam Medical College has the pride of having the first Radiology department in India, as in 1910 two X-Ray machine (One 10MA and another 15MA) was bought from England, only 15 years after the discovery of X-Rays by Professor Wilhelm Conrad Roentgen in 1895-96. These two were the first X-Ray machines in India.

Apart from medical, the other higher fields of learning in the district are Pharmacology, Geology and Applied Geology and Petroleum Technology. All these courses are offered by Dibrugarh University, which was established in 1965.

Beside the University, other centres for learning are:

  1. Dibrugarh Poly-technique (offering various diploma courses in Electrical, Civil and Mechanical fields).
  2. Regional Medical Research Centre -RMRC (a centre for scientific and research in Bio-medical sciences where major health problems and its causes are studied).

The district came to national prominence for education in 2009 with Gaurav Agarwal of the Assam Valley School topping the country in the Class XII board examinations conducted by the Council for the Indian School Certificate Examinations.[12] [13] [14]
