After graduating from Wasilla High School, she attended several colleges before earning a Bachelor of Science degree in communications-journalism from the University of Idaho in 1987. Before entering politics, she worked briefly as a sports reporter for local Anchorage television stations and competed in beauty pageants, finishing as a runner-up for Miss Alaska in 1984.
Her political career began modestly. In 1992, she won a seat on the Wasilla City Council, and four years later, at the age of 32, she was elected mayor of the small city, a position she held until 2002. During her time as mayor, she developed a reputation as an outsider willing to challenge established interests — a theme that would define her entire political brand. She went on to serve on the Alaska Oil and Gas Conservation Commission, where she led an investigation into ethics violations involving members of her own party, cementing an early image as a reformer unafraid to take on entrenched power.
