The 1970 series of the high school included 4 classes of 25 students each, with a program of 4 hours a day in the morning from 8:30 to 12:30. The first 2 years included an intensive specialized program, studying the internal structure of the computer, representation, organization and management of data, algorithms and logic schemes, computers, assembly languages (Asembler; Asiris), programming in Cobol, Fortran and a laboratory of digital electronics and programming of Fc15 Accounting Billing machines, etc. Starting in 1972, elements of general culture and economic and organizational sciences were introduced.

Professors were: Burcescu Theodor/Gibi/ (Director); Barbulescu Constanta, Nicolaiescu Speranta /Mobutu/ (Romanian Language and Literature); Iancu/Maslinuta/, Ilish Virgil, Lazarescu Petre/Bibi/, Mitrache Ion/Mitrelu/, Nedita Nicolai/Codita/, Radoi Ion (Mathematics); Bocanete Ileana, Ilie Gheorghe, Ovanez Victoria, Popa Ioan (Physics); Pop Livia (Data management Systems); Mogos, Covaci (Sports); Vancusi Eva (Chemistry); Dediu Silvia (Zira) (Political Economy); Ulieru Elena (Philosophy); Serban Nicolaie(Sheriff), Cojan Iuliana (French Language); Bulgaru Dorina, Melinescu Cecilia, Tanasescu Anca (English Language); Bucur Marioara (Management); Oprescu Daniela /Pestisoru/ (Operating Systems); Popescu Ilie/2K/, Fotescu Cezara (Fortran), Dumitrescu Mihai /Creasta/ (Cobol); Vasiliu Calin (Felix 256); Theodorescu Alexandru /King-Kong/ (IPSEC); Marinescu Sorin (Algorithms); Vasiliu Adela (Information Supports); Jitaru (Assiris); Coconoiu, Lucaci (FC-15)..

In the basement, the computer technology laboratory was developed, including terminals, card punches, accounting billing machines, office computers, which was permanently adapted by ICI care.

In 1977, its name was changed again to "High School of Mathematics and Physics No. 1", then, in 1991 "High School of Informatics", so that in 1997 it became "Tudor Vianu National College of Informatics".

Just four years later, the institution changed its name once more and became known as the Mathematics-Physics High School no. 1 (Romanian: Liceul de matematicǎ-fizicǎ, nr. 1). The development of microprocessors as Intel 8080 or Zilog Z80 made possible the appearance of micro-computers as M118, HC-85, Tim-S, Cobra etc., operating inside 64 k of memory with external cassette data support or flexible disks, that came to replace the previous multi-head cartridges as ISOT 1370, etc.

At the end of 1989 the so called "Romanian Revolution" took place, being a time of changes in computer science too. The era of Z80 or Intel 8080 was in the last throats, and a new liberalization in Computer market was predicable.

In 1991, just two years after the Romanian Revolution, the school was renamed High School of Computer Science. Since 1997, the institution uses the name of a famous Romanian art critic, poet, philosopher and translator: Tudor Vianu. The reasoning is still unclear, because the Vianu's domain of excellence was in a different domain than computing, but the excellence remained a common factor. The graduates of Computer Science High School aspire the same level of excellence as Vianu obtained inside National culture. By 1992 the PC286 diagrams were published by IBM and the era of personal/professional computers started.

The evolution of Internet, parallel machines, super-computers challenged new changes in the High-School.

In 2007, due to its last admission rating of 9.51, CNITV was ranked first in Bucharest. One year later, its last admission rating suffered a significant drop to 9.17, and was ranked on the 5th place. This drop was believed to have been caused by the Romanian Government's decision to change the entrance examination methodology.[2] In 2009, the high school was ranked 2nd after Saint Sava National College, in 2010 it was ranked 4th, due to its 9.32 last admission rating, and in 2011 was also the 4th, with 9.42 last admission rating. And after 9 years, in 2018, the high school was ranked once again the 2nd high school in the country, after Saint Sava National College

The Tudor Vianu National High School of Computer Science has been participating in two 2 different projects in recent years. The projects were coordinated by Iulia Manicea.

CNITV also took part in other Academic Competitions. In 2009 and 2010, two teams participated in the NASA Great Moonbuggy Race,[3] a competition held in Huntsville, Alabama since 1994. The students had to build a vehicle resembling the Lunar Rover used on the Moon during the last three missions of the American Apollo program and then race it to the finish line.

The Romanian Master of Mathematics and Sciences [5] (formerly known as the Romanian Masters in Mathematics), also referred to as RMMS is an annual international competition dedicated to students at preuniversitary level. It is organised by the Tudor Vianu National High School of Computer Science in collaboration with the Sector 1 town council.

The first Romanian Master of Mathematics [6] took place in 2008. At the 2012 RMMS, there were 14 participating countries: Romania, Russia, Brazil, United Kingdom, United States, Serbia, Bulgaria, Italy, China, Kazakhstan, Republic of Moldova, Ukraine, Poland, Hungary. There was no RMMS competition in 2014.
