Senate Bill 631, also known as House Bill 326, proposes to establish March 3 of each year as "Sister Sandra Smithson Day" in Tennessee. This day is intended to honor Sister Sandra Olivia Smithson for her significant contributions to education, particularly for low-income and underprivileged children, including Black and Latino communities. Sister Smithson, who founded Nashville's first charter school, Smithson Craighead Academy, dedicated over sixty-seven years of her life to religious service and educational advocacy, impacting countless lives through her work.

The bill amends Tennessee Code Annotated, Title 15, Chapter 2, by adding a new section that designates this observance day, while clarifying that it is not a legal holiday as defined in section 15-1-101. The act is set to take effect upon becoming law, emphasizing the public welfare. The language of the bill highlights Sister Smithson's legacy and her role in educational reform, particularly her efforts in founding a charter school and advocating for educational opportunities for children in need.
