The Chasnalla Academy came into existence on 9th Feb. 1973 due to the persistent efforts of a small section of intellectuals who realized the need for an educational institution to impart quality education to the wards of IISCO employees as well as non-IISCO local population of Chasnalla which they were deprived of till then.

Ever since that period, the Academy has been making longer strides at a faster pace towards progress and achievements of academic goals despite stiff challenges on financial front. Subsequently in 1975, the sincerity and commitment in the efforts of staff have led the IISCO management finally to grant the aided school status to the Academy. In 1983, the Academy could successfully obtained the affiliation from Central Board of Secondary Education, New Delhi. Over the years, the school due to the untiring and dedicated efforts of a wonderful team of trained and experienced teachers has employed itself into a vibrant Co-educational institution for imparting quality education in English madium. Subsequent years witnessed the augmentation of many infraatructural facilities and ultimately the up-gradation of the school into Senior Secondary level from the Academic year 2005-2006.
