Before her freshman year in high school, Augustus was featured on the cover of Sports Illustrated for Women, with a headline that asked, "Is She the Next Michael Jordan?" Augustus played for Capitol High School in Baton Rouge, Louisiana, where she was named a WBCA All-American.

During her collegiate career with the LSU Lady Tigers, the two-time All-American won the Naismith College Player of the Year, Wooden Award and Wade Trophy in 2005 and 2006 while leading the LSU to three straight Final Four appearances.

Her uniform number (33) was retired by LSU on January 9, 2010, making her the first female athlete in school history to receive that honor. In January 2023, she became the first female athlete in school history to have a statue of her on the school campus; that statue is in front of the school’s basketball training center next to statues of Bob Pettit, Shaquille O'Neal, and Pete Maravich, who also played for LSU.
