Michelle Obama and the first lady of South Korea are heading to Fairfax County’s Annandale High School on Thursday morning to speak to students and watch a musical performance.

The excursion is part of an official state visit by South Korean President Lee Myung-bak and his wife, Kim Yoon-ok, who will be guests of honor at a White House state dinner Thursday night.

Annandale is an inside-the-Beltway community where many Korean American families live and run businesses. Its high school is among Fairfax’s most diverse — there is no majority racial or ethnic group — and it consistently posts high scores on state math and reading tests.

Vincent Randazzo, principal of Annandale High School, said about 550 students with good grades and discipline records were chosen by lottery to attend an assembly with the first ladies. They will listen to a performance by fellow Annandale students, virtuoso violinist Jennifer Koh and the Annandale-based World Children’s Choir.

Afterward, Obama will deliver remarks.

This is not the first time the school has served as a backdrop for national political figures. In 1997, President Clinton’s Advisory Board on Race held a public conversation about diversity in America at Annandale.
