Today, graduating seniors at Washington Mathematics Science Technology Public Charter High School will hear advice from First Lady Michelle Obama at their commencement at Howard University. Student Jasmine Williams first wrote to Obama asking her to speak, and has been chosen to introduce her to the students. “I am probably going to practice hundreds more before Wednesday,” Williams told WJLA about her introduction. The charter school is D.C.’s only open enrollment public school to meet Adequate Yearly Progress targets under No Child Left Behind in both math and reading for the last two years.
