He had dropped out of school after the ninth grade, eonline.com reports.
"I was fortunate to find out I could attend high school online," Wahlberg wrote in an op-ed in Huffington Post.
"For almost a year, I've been taking classes and studying any chance I could get-on the set, traveling for work and at home. It has been both humbling and challenging, but I'm happy to report that I am officially a high school graduate," he added.
