Since the emergence of Pakistan on the map of the world, the examinations pertaining to the Matriculation and Intermediate level were conducted under the aegis of University of the Punjab. However, through the promulgation of the Punjab University Act (Amendment) Ordinance 1954, the Board of Secondary Education, Punjab was established in the province which took from the said University control of examinations of Secondary, Intermediate and Pakistani & Classical Languages. The first-ever examination for these stages was conducted in the year 1955.

1. At the time of its inception in 1954, the Board inherited vast territorial jurisdictions for conducting examinations in the provinces of Punjab, Baluchistan, Azad Kashmir and Northern Areas. To accommodate overseas candidates, the Board also constituted examination centres at Kuwait and Nairobi (Kenya).
2. Current jurisdiction of the Board of Intermediate & Secondary Education Lahore has been confined to the districts of Lahore, Kasur, Sheikhupura and Nankana Sahib.

Owing to tremendous increase in the candidature, two more Boards were established at Multan and Sargodha under West Pakistan Boards of Intermediate and Secondary Education (Multan & Sargodha) Ordinance No.XVII of 1968. As a result of further bifurcation, Boards were also established at Rawalpindi,Gujranwala and Sahiwal. The re-construction of the Board of Intermediate & Secondary Education, Lahore has been done through the Punjab Boards of Intermediate & Secondary Education Act 1976 (lately amended by Punjab Ordinance No.XLVII), and presently in the administrative setup of the province, Nine Boards are functioning at division level.

The Chairman exercises control over the office of the Board as its principal executive and academic officer and also presides over the meetings of the Board. He is also assisted by two officers of the Board, namely the Secretary and the Controller of Examinations, in administrative matters as well as those related to examinations, as shown in the following organizational chart;

To promote the cause of education through conducting examinations in an extremely fair, unbiased, transparent & judicious environment so that our educated nationals may be able to contribute meaningfully in the competitive world.
