TRUST was a four-year (2003-2007) NSF-funded collaboration between the Museum and Lehman Colleges of the City University of New York. Its goal was to increase the number of certified Earth Science teachers in the state and to establish a collaborative model for formal/informal urban science teacher education. This evaluation was conducted by Dr. David L. Silvernail of the Center for Education Policy, Applied Research and Evaluation at the University of Southern Maine.
