In June 1948 3 rooms of the girls Primary School of New Delhi Municipal Committee at Lodhi Colony were taken on rent and the new School started Functioning from there. Ms. Renu Mukherjee was appointed as the Head Mistress.

After almost two months, on 8th August 1948 with the initiative taken by the Chairman of the Co-ordination Committee D. L. Majumdar, Dr. Shyama Prasad Mukherjee officially inaugurated the School.

In September 1948 a General Body of the School was formed whose members included the members of the Co-ordination Committee, Donors to the School Fund and the Parents of the Students studying in the School. On 5th September 1948 the General Body elected a Managing Committee consisting of 13 members ? D. L. Majumdar was elected the President of the Committee, G. C. Ghosh Vice-President, S. L. Banerjee Secretary, S. K. Roychowdhury Joint Secretary and D. C. Bhattacharya Treasurer. General Body gave the following instructions to the newly elected Managing Committee :

Obtaining Approval from the Directorate of Education.
Arranging a piece of Land in the vicinity of Lodhi Colony / Lodhi Estate to house the School.
Preparation of a Draft Constitution for smooth Administration of the School.
It is felt that it would be proper to mention at this stage that since in the main school at Rajabazar, both bengali as well as non-bengali speaking students were studying together it was decided that the same system would be followed at the branch school also.

The Managing Committee now started their work in full steam and within a short period of time, in May 1949 got the approval of the Primary Section (I to V) from the Directorate of Education. After this in the Month of November 1952 the Secondary Section (VI to VIII) was approved by the Education Department and finally in May 1956 the Education Department gave their approval for the Higher Secondary Section (IX to XII).

The Managing Committee was very fortunate in their effort in another matter too. In August 1953 the Land Development Officer allotted to it 3.5 acres of land in Lodhi Estate Area on 99 years lease.

With passing of time, the newly establish school at Lodhi Colony was slowly becoming quite popular with the residents. There was lot of pressure on the Management for admitting more and more students. In view of this the Committee decided to shift the school to its own land in Lodhi Estate. The school started functioning on its own premises from the year 1954.

The effort of the Managing Committee in motivating the bengali community of Delhi for financial support succeeded to a great extent. Besides this financial helps also came from Govt. of West Bengal.

With the money in hand the Managing Committee now decided to start construction of the school building. The foundation stone of the building was laid by Dr. Radha Krishnan, Vice-President of India on 6th March 1960. The double storied building was completed in the year 1961.

Ms. Renu Mukherjee who was Head Mistress right from the inception, had brought up the school to the present stage with lot of love and care. She left the services of the school in the year 1955. She would be always remembered fondly for her contribution in the development of the school. In the year 1956 Ms. Kamal Rani Mitra was appointed as the first Principal of the school. By this time the school was already recognized as a Higher Secondary Institution by the Department of Education.
