After completing her schooling, she pursued formal education at the Government College of Art & Craft in Calcutta, a renowned institution that has nurtured many prominent artists. During her time there, she was fortunate to study alongside future luminaries of the 1960s art scene, such as Dhiraj Choudhury, Sunil Das, Jogen Chowdhury, and Shyamasree Basu. These relationships not only enriched her learning experience but also fostered a creative camaraderie that would influence their work in the years to come.

Under the mentorship of Satyen Ghosal, Anita honed her skills and artistic voice. In her second year, she was guided by Gopal Ghosh, whose liberal teaching approach allowed her to experiment with colors freely. This encouragement was pivotal; Ghosh’s support can be seen as a turning point in Anita’s development, particularly in her use of watercolors, a medium she would become known for.

In 1959, Anita joined the Society of Contemporary Artists, marking her entry into the broader art community. Her first solo exhibition, arranged by the society in 1962, was a significant milestone, showcasing her talent to a wider audience. This early exposure was instrumental in establishing her reputation as an emerging artist.

By 1969, Anita became a member of 'Calcutta Painters,' a collective that played a vital role in the modern art movement in India. Through this affiliation, she participated in numerous group shows and solo exhibitions, both in metropolitan cities across India and internationally. Notable venues for her exhibitions included AIFACS in New Delhi in 1963, the Academy of Fine Arts in Calcutta in 1964, the Jehangir Art Gallery in Bombay in 1966, and the Sarala Art Centre in Madras in 1969, among others. These exhibitions not only showcased her evolving style but also solidified her position in the contemporary art scene.

Overall, Anita Roy Chowdhury’s journey reflects a blend of innate talent, supportive mentorship, and active participation in the vibrant art community, allowing her to make a significant impact in the world of art.
