The PSBB branch of K.K Nagar branched out of the main school in 1976 as part of the expansion programme, to meet the ever growing demands for admission. It has established itself as a strong educational edifice in the city of Chennai, under the stewardship of Dr. Mrs. Y.G.Parthasarathy and will remain a timeless institution in the annals of education, with the dedicated efforts of the Principal Mrs. Hamsa Ramdas, Sr. Principal, and the Sr. Vice Principal Mrs. Chandra Srinivasan, Miss J. Balambal, First Headmistress who continues to be a source of inspiration to the school since 1976 and the dedicated team of teachers.
Today 25 years later, PSBB K.K.Nagar is a colossal institution of international repute. The school celebrated the momentous occasion of its Silver Jubilee in its mission to afford quality education to society with a year long programme. The celebration was flagged off to a start by a formal inaugural function. The celebration included a cultural programme on 31st July 2001, presenting a glimpse from the cultural item of yesteryears. It was a fusion of talents that passed out of the portals of this institution with that of the blossoming young ones and the teachers - when the staff, students and the alumni performed in unison. Mr. Bernard J. Alter U.S. Consulate General, Chennai was the chief guest and Mrs. Pat Alter released the Silver Jubilee Souvenir. Dr. R. Natarajan, Director, IIT, Chennai was the Guest of Honour.
The Silver Jubilee celebration was a moment to rejoice, to cherish past glory and achievements, to accept present day challenges and welcome the future with greater accountability. PSBB K.K.Nagar will undoubtedly stride ahead in the new millennium.
