In 2007, James Dierke, then the principal of the Visitacion Valley Middle School in a troubled neighborhood in San Francisco, was determined to improve both the quality of education and student behavior in his school. He adopted a system called the Quiet Time Program, developed by the David Lynch Foundation for Consciousness-Based Education and World Peace. The program, implemented in partnership with the nonprofit Center for Wellness and Achievement in Education, involved introducing two 15-minute periods of quiet into the school day. During those times students could either practice Transcendental Meditation, which is taught as part of the program, or engage in other quiet activities like silent reading.
