Brown was required to take the once-a-week class for one year as part of his plea deal for attacking his former girlfriend during a heated argument in a car in February 2009.
He was also sentenced to 180 days of community labor, placed on five years probation and ordered to stay away from Rihanna.
"I have enough self-respect and decency to be proud of accomplishing this DV class," MTV.com said Brown tweeted Tuesday morning. "Boyz run from their mistakes. Men learn from them!!! thx."
