Warner Bros. TV has opened the application process for its third annual Television Directors’ Workshop, a program designed to give aspiring and diverse directors the chance to break into primetime television.

The WBTV Directors’ Workshop aims to prepare directors from other mediums — feature films, music videos and commercials — for the transition to episodic TV, as well as to seek out fresh, diverse voices from within the creative community, to help provide increased opportunities to women and ethnic minority helmers.

The 12-week master class course will run from May through August and is taught by director and author Bethany Rooney, with other industry professionals providing insights as guest speakers. Past participants include Zetna Fuentes, who went on to direct episodes of “Pretty Little Liars” and iZombie”; Antonio Negret, who subsequently helmed episodes of “Arrow,” “The Flash” and the “DC’s Legends of Tomorrow”; and Richard Speight, Jr., who made his episodic directing debut on “Supernatural” this season.

Applications will be accepted from January 20 through February 11 via the studio’s Television Workshop website, which also contains information on WBTV’s Writers’ Workshop, which counts scribes including Terence Winter (“Boardwalk Empire”), Marc Cherry (“Desperate Housewives”), Greg Garcia (“My Name Is Earl”) and Felicia Henderson (“Soul Food”) among its alums.
