This coming Friday marks the 20th anniversary of the Convention on the Rights of the Child, the most comprehensive treaty on children's rights. The convention has been ratified by nearly every country in the world, except for the United States. The convention would fill current gaps in U.S. laws, and provide all children in America with the same robust protections that children in 193 countries are already entitled to.

According to 2006 data collection, 3.3 million students received out-of-school suspensions and more than 100,000 students were expelled from school. Students of color, , bear the brunt of this over-criminalization.

As we celebrate the 20th anniversary of the Convention on the Rights of the Child, we must imagine an of human dignity, freedom from discrimination, and the full development of every child.
