Sir Tashi Namgyal (Sikkimese: བཀྲ་ཤིས་རྣམ་རྒྱལ་; Wylie: Bkra-shis Rnam-rgyal) (26 October 1893 – 2 December 1963) was the ruling Chogyal (King) of Sikkim from 1914 to 1963.

Born in Tibet and crowned by the 13th Dalai Lama, Thubten Gyatso, he was a strong advocate for closer links with India.

The present Academy was shaped out of Sir Tashi Namgyal High School which was affiliated with Calcutta University.

A Governing Body for the administration, management and control of Sir Tashi Namgyal High School, Gangtok was constituted under the Chairmanship of Maharaja Kumar Saheb.

I am sure that under able guidance of Shri Langer this school will develop into an institution where not only future citizens of Sikkim will learn to serve their country, but where sectarianism, communalism, bigotry, small mindedness, pursuit of power will have no place.

He said, "In the past it has been difficult for children of poor parents to enjoy the advantage of the best possible schooling as they could not afford admission to the more highly organized institution in Darjeeling, Kalimpong and elsewhere.

But the Darbar will ensure that there will be ample scope for meritorious children of poor parents to gain admission to the Academy on the result of Competitive Scholarship Examinations.

Maharaja Kumar Palden Thondup Namgyal, the Chairman of the Governing Body, on the occasion of the opening of the Annex said, "The Principal objective of the Darbar has been to provide education that will be consistent both with the culture, heritage and economic conditions of Sikkim.

Increase in students roll necessitated another hostel in the two-storied building then known as Northern Block, half for Nepali boarders and half for Bhutia-Lepcha boarders with a dining hall at the site now occupied by Science Block with separate kitchens for Nepali and Bhutia-Lepcha boys.

The old junior school block where Lower Kindergarten classes were held then served as the Hall with a capacity of approximately 300 people with a low stage.

In 1964 the idea of reorganizing Tashi Namgyal Academy on public school lines as coeducational institution was implemented.

This policy, it was hoped, would enable to build up an institution in which even through medium of instruction and the first language English it would remain Sikkimese in its tradition and culture.

In March 1966, Tashi Namgyal Academy was reorganized along Public-School lines with English as the medium of instruction and the first language.

This idea led to the shifting of Sir Tashi Namgyal Higher Secondary School to the Development Area in Gangtok, along with approximately 14 members of teaching staff and majority of students especially from classes VII and above.

The major games played were football, volleyball, badminton, table tennis, basketball, hockey, netball, baseball, and cricket.

The annual Inter House 3-day Track and Field sports meet is called the Mini Olympics and has the ceremonial lighting of fire too.

Some of the elder staff of Higher Secondary School who had been retained, gallantly rose to meet the pressing demands of the situation.

Langer, took over the responsibility of organizing the hostel and its routine so that it may be ready to receive the boarders when they come a day before the start of the session in March 1966.

A new matron took over charge of the Hostel leaving Mrs. Langer free to devote herself to teaching work, two more teachers were appointed, one for additional section of K.G.

[3] The institution aims to provide sufficient academic knowledge for a child to be able to meet the standards required to complete their college course without much strain.

The school has a rectangular-shaped compound, measuring about 12 acres (49,000 m2) bound by the National Highway (NH-10) to Nathula in the southwest and the road leading to Raj Bhavan in the northeast.

Starting from the Upper Main Gate down to the Lower Main Gate there is an open air-theatre, football ground, swimming pool, principal’s bungalow, three multi-storey buildings, 27 single and double unit staff quarters spread all over the school campus, two hostels for boys, one hostel for girls including hostel staff quarters, one kitchen and a hostel dining hall, a large auditorium with a capacity of 600 including a gallery, seven double/three-storey buildings for classrooms, Science Block (previously consisting of laboratories for Physics, Chemistry, Biology and Home Science, now shifted to the new Annex Block since 2006), Common Rooms, Workshops and an Administrative Block.

There are three athletic fields, one each for Football, Volleyball, Basketball and well laid out flower beds, sprawling lawns and green slopes spread all over the campus.
