Disney XD released a press release about the renewal:
"Disney XD kicks into high gear and orders a third season of the top-rated comedy series “Kickin’ It,” it was announced today by Adam Bonnett, Senior Vice President, Original Programming, Disney Channels Worldwide. Season Three of the popular series will follow the crew of lovable misfits at Bobby Wasabi Martial Arts Academy as they embark on new adventures outside the dojo. Production resumes in Hollywood in January.
“Disney XD viewers have clearly connected with this series about friendship and martial arts,” said Bonnett. “We look forward to telling more stories in Season Three, where our characters use their martial arts knowledge and skills out in the world, taking their ‘mojo’ out of the dojo!”
