There is a dramatic shortage of Black male teachers in U.S. classrooms and Education Secretary Arne Duncan says he is ready to do something about it.

There are more than 5 million teachers in public schools across the country. But, Duncan told CNN last month that of the 200,000 new teachers hired each year nationally, less than 2 percent, or 4,500, are Black males.

To help increase those numbers, Duncan said he plans on embarking on a tour this fall of historically Black colleges and universities to drive home the need for a larger presence in schools of African-American male instructors.

โ€œAs a country we have a huge challenge to make sure many more of our students and more of our young Black boys are successful,โ€ Duncan told CNN. โ€œOur graduation rates have to go up dramatically and our dropout rates have to go down. to get there, Iโ€™m convinced we have to have more men of color teaching, being role models and mentors.โ€

In Washington, D.C., where the majority of residents are African-American, the school system reported in 2008 that 18 percent of its 3,800 teachers are men and of that number, about 9 percent are Black males. In Virginia, 2.6 percent of its more than 100,000 teachers are Black men.
