[2] Devnani joined the Rashtriya Swayamsevak Sangh (RSS) at a young age and later its student wing Akhil Bharatiya Vidyarthi Parishad (ABVP), serving as the Rajasthan state president of the latter for nine years.

[6] He plans to introduce Rajasthan heroes such as Maharana Pratap in the school textbooks, correcting the alleged "anti-Hindu agenda" of the previous Congress government.

[citation needed] Among his measures are celebrating Basant Panchami in schools, singing Saraswati vandana and performing surya namaskar every day.

However, his measures to introduce compulsory Saraswati puja and surya namaskar have invited opposition from the schools run by the Arya Samaj, Muslim community and the Christian missionaries.

[9] In April 2015, Devnani hit the headlines with stories that reported that Isaac Newton, Pythagoras and Akbar are being eliminated from the school textbooks.

[10] In March 2016, Devnani announced that "major changes" were being made in the school curriculum, by including the biographies of freedom fighters, so as to ensure that "no one like Kanhaiya Kumar" would be born again.
