Grades 3, 4 and 5 were continued at the Rankoth Viharaya premises and it was popularly called town branch of the college.

The plot of land between the main college and the play ground was eventually acquired by the Education Department.

In 1992 due to inclement weather the retaining wall of the Rankoth Viharaya collapsed damaging the main hall of the town branch.

The Old Boys Association, parents and well wishers constructed 18 semi-permanent class rooms and the Town Branch was amalgamated to the main college.

On 26 December 2004 the tsunami which destroyed the southern and eastern coastal areas damaged part of the semi-permanent buildings of the college.
