Until the outbreak of the World War II, the school had boarding facilities, mainly for students from out of town.

The students are spread across eleven standards or grades, from Grade-1 (formerly Kindergarten of KG) to Grade-11 (formerly Tenth Standard, colloquially sei-dan) For many years, TTC students have a tradition of putting the right finger at the lip and say "Kyan Mar Shwin Lan Par Sae" *_ကျန်းမာရွင်လန်းပါစေ ဆရာ/ဆရာမ_* – (good health to you) to the teachers.

All uniforms are of the same colour – a white shirt or blouse, with a green garment for the torso.

It ranks the highest overall in Burmese High School in the Myanmar University Entrance exam, conducted by the Myanma Examination Board.

TTC has won medals in national and international competitions, such as South East Asian Games.

In order to cope with the loss of nearly three-quarters of its classroom capacity, a building and renovation programme was implemented, resulting in the renting of the former University of Yangon (Hlaing Campus), which was also known as Regional College Number 2 (or RC-2), and the building of a new school wing.

With the rising use of the internet and government promotion of information technology, two IT labs have been added to the campus facilities, though they are not frequently used, due to the overwhelming student population.
