H.R. No. 33 is a resolution recognizing April 2, 2025, as World Autism Awareness Day in Texas. The resolution highlights the importance of promoting understanding of autism and the challenges faced by individuals with autism spectrum disorder (ASD). Established by the United Nations in 2007, World Autism Awareness Day aims to raise public awareness about autism and emphasize the need for improved quality of life for those affected by the disorder. ASD presents a range of health conditions that can lead to social, communication, and behavioral challenges, with symptoms varying widely among individuals.

The resolution also notes a shift in the approach to autism, with many medical professionals now embracing the neurodiversity paradigm. This perspective focuses on supporting individuals with autism rather than seeking to "cure" the condition, thereby helping to restore dignity and self-esteem. The House of Representatives encourages all Texans to foster an environment of compassion and acceptance for those impacted by autism, affirming their commitment to this important cause. The resolution was adopted by the House on March 31, 2025.
