The FBI’s National Academy—a prestigious 11-week educational program for law enforcement officers from around the world—graduated its 270th class today, and on hand to congratulate the graduates were Director Christopher Wray, Attorney General Jeff Sessions, and President Donald Trump.

“I’d like to extend a special welcome to President Trump and Attorney General Sessions,” Wray said, addressing the 222 students in this session’s class, who represent 49 U.S. states, 20 countries, four federal agencies, and three branches of the U.S. military.

“For more than 80 years,” Wray said, “this program has served as a bridge between state and local law enforcement to international law enforcement. Today, you join the ranks of more than 50,000 graduates from more than 170 countries.”

Founded in 1935, the National Academy program offers mid-career law enforcement leaders an advanced training program at Quantico, Virginia, the same location where the FBI trains its agents. National Academy students take courses in subjects ranging from behavioral science to counterterrorism to intelligence theory and engage in intense physical training. Just as importantly, they network with their peers.
