Expansion of classes and academics

This school was originated as boys school in Sinhala mediun, The students who completed their primary education got admitted to the college. It is them reported to have charged school fees from students. The subjects taught in the college were English, Latin, Geometry, Algebra, Geography, Pali and Sanscrit and the students were directed _ the exams conducted by Cambridge University.

Alma mater sails in to a new chapter with the introduction of the tertiary education advanced level arts classes were conducted for the 1st time in 1943 while entrance to the university was passible from the year 1945. Whit expansion of studies advanced level science was conducted in 1957. As a result a student entered in to the University in the following year. It was Jayatissa Bandara to be the first University Entrant in science steam While S.M. Banduseela got through in Bio Science. Palitha Kumara singhe was the first medical student in 1960. In a later year, in 1994 students got opportunity to offer agriculture for Advance Levels. As commerce subjects too introduced in 1960’s the number of university entrants from every fields was remarkably high. For the faculty of commerce, Management, Dental and Medical, Students enrolled in years that followed. It was rewarding to introduce music as an aesthetic subject in 1960’s for while dancing started somewhere in junior level 1980’s. Aesthetics subjects were introduced for A/L in 1990 onwards. No parallel classes were possible then. Since the number of students in a senior class was not more than 25 this situation changed in the course of time having two parallel classes in 1940’s and 3 classes in 1950’s for each grade. In 1970 this jumped in to 8 parallel classes. By 2000 and 2003 classes of grade 6 and 10 increased in leaps and bound s having 10 classes for each grade respectively. At the dawn of 21st century the average rate of students in a class leapt over 45.

Exam results

It was reported that most of the students who offered Cambridge (Junior/Senior) exams got through even in this outset. As students excelled in London matriculation in 1938 a holiday was declared as honor for students.

During that period nearly 20 or 25 students sat the senior level exams while 35 students for junior levels. Remarkably 21 had passed at senior level out of 27 in 1941.Collegekept up this record for a decade (1940’s) annual with the establishment of university of Ceylon there was a rapid increase for the university entrance yearly It was five ten in the outset. This number went up to 14 dramatically the following year. In the 5th decade this figure remained between 20-30 while it increased rapidly to 100 in the 6th decade.

Today it is the essence of revolution for Dhamso to make a steady representation in education sphere having students in all the universities and in other education institutions. Replacing old thatched houses with storey buildings in a large area school acquires a dignity today. Although school was built up merely on donations in the beginning state allocated funds for many new buildings after 1961

We then reflected on the glorious past of Aesthetics disciplines which transferred the present generation by its creators. In this field students showed great performances. After 1987 Students secured all island records for the first time. In 2002 Two pupils of the college participated in a traditional upcountry dancing event “Vs banduma” bringing great honor to the college. They keep up with these performances. They also showed a keen interest and ability in drama as well

Reflecting on the past

The first emblem belongs to the period of E.A.Jayasooriya, the principal. The emblem you see today in the one reproduced by Mr. D.D. wijerathna a former principal of the college. He was the who introduced college colours. the previous colours were rend and indigo. Then college song was composed by master Ananda Samarakoon, the composer of National Anthem also belonged to this age. Another worthy course was the establishment OBA during this period it was reported in log by Mr. D.T. Wijerathne who was the pioneer of this enterprise.

Dhamso with its proud history occupies a unique place in the arena of education in Sri Lanka for ever.
