Zachary David Alexander "Zac" Efron(born October 18, 1987) is an American actor and singer. He began acting professionally in the early 2000s, and became known to young audiences after his roles in the Disney Channel Original Movie High School Musical, the WB series Summerland, and the 2007 film version of the Broadway musical Hairspray. In 2007, right before the release of High School Musical 2, Rolling Stone declared him the "poster boy for tweenyboppers" and featured him in their late August 2007 issue.

Early life and background
Efron was born in San Luis Obispo, California and later moved to Arroyo Grande, California. His father, David Efron, is an engineer at a power plant, and his mother, Starla Baskett, is a former secretary who worked at the same power plant. Efron had a self-described "normal childhood" in a middle class family. He has a younger brother, Dylan. Efron is of Jewish ancestry and is an agnostic, having never been religious. He has said that he would "flip out" if he got a B and not an A in school, and that he was a class clown. Although self-described as not academically gifted, he remained focused enough to achieve an overall GPA of 4.3. Efron's father encouraged him to begin acting when Efron was eleven. He subsequently appeared in theater productions at his high school,worked in a theater called The Great American Melodrama and Vaudeville,and began taking singing lessons. Efron performed in plays such as Gypsy, Peter Pan, Or The Boy Who Wouldn't Grow Up, Little Shop of Horrors, and The Music Man. Efron was recommended to an agent in Los Angeles by his drama teacher, Robyn Metchik (the mother of actors Aaron Michael Metchik and Asher Metchik). He was later signed to the Creative Artists Agency.

Education
Efron graduated from Arroyo Grande High School in 2006,and was then accepted into the University of Southern California, but he deferred his enrollment while he worked on film projects. He plans to return at some time. Efron also attended Pacific Conservatory of the Performing Arts, a community college located in Santa Maria, California, which provided him with the opportunity to perform as a "young player" during the years of 2000 and 2001.
