The Chinmaya Mission, Tattamangalam was established by a handful of committed devotees of Swami Chinmayanandaji.
Swami Chinmayanandji sent few sewing machines sponsored by a devotee in Mumbai. These sewing classes that were organised spurred the Mission to think on lines of opening a school. Thus Chinmaya Vidyalaya Tattamangalam was conceived
|June 12th 1977||
The Vidyalaya was formally established in a rented building at Western Village, Tattamangalam .
The Vidyalaya was shifted into its own building which currently houses the Kindergarten Block and Play School .
|In 1980 s||
Visit of H.H.Swami Chinmayanadaji to the Vidyalaya and in his address to the public that the school will grow into a Senior Secondary School inspired the mission to affiliate the Vidyalaya to the CBSE .
The Vidyalaya was granted affiliation and became a Secondary School and presented its first batch of class 10th for public examination.
The main Vidyalaya moved into the 5.2 acre plot which now houses the present Vidyalaya and has upgraded to a Senior Secondary School and had presented the first batch of class 12th students for the Examination in 2012.
