Question: is anakin a jedi master in episode 3

Answer: No, Palpatine appoints Anakin to the Jedi Council as his representative, but the Council declines to grant Anakin the rank of Jedi Master and orders him to spy on Palpatine, causing Anakin's faith in the Jedi to diminish significantly. Palpatine tantalizes Anakin with secret knowledge of the dark side of the Force, including the power to save his loved ones from dying. Meanwhile, Obi-Wan travels to the planet Utapau, where he kills Grievous, and Yoda travels to Kashyyyk to defend the planet from invasion. Tempting Anakin, Palpatine eventually reveals that he is the Sith Lord Darth Sidious, saying that only he has the knowledge to save Padmé from dying. Anakin reports Palpatine's treachery to Mace Windu, who confronts and subdues the Sith Lord, severely disfiguring him in the process. Fearing that he will lose Padmé, Anakin intervenes on Palpatine's behalf and severs Windu's hand, allowing Palpatine to throw him out of a window to his death. Anakin pledges himself to Palpatine, who dubs him Darth Vader. Palpatine issues an order for the clone troopers to kill their Jedi commanders and dispatches Vader along with a legion of clones to kill everyone in the Jedi Temple. Vader then massacres the remaining Separatist leaders hiding on the volcanic planet Mustafar, while Palpatine addresses the Galactic Senate, transforming the Republic into the Galactic Empire and declaring himself Emperor. Having survived the chaos, Obi-Wan and Yoda return to Coruscant and learn of Anakin's treachery.
