Mexico's President Enrique Pena Nieto pauses during a speech at the National Palace where he signed into law a plan to overhaul his country's public education system, in Mexico City, Monday, Feb. 25, 2013. The law which was approved by Congress in December, calls for creation of a professional system for hiring, evaluating and promoting teachers without the "discretionary criteria" currently used in a system where teaching positions are often bought or inherited.
