"The national evaluation of the G.R.E.A.T. program used two separate studies to assess its effectiveness: a 1-year cross-sectional study and a 5-year longitudinal, quasi-experimental study. Two years into the 5year study, students were not exhibiting the promising returns indicated by the 1-year study. In response, a national evaluation team assessed and revised the program. Greater emphasis was placed on incorporating teachers into the lesson plan to enhance the reinforcement of lessons and skills learned. The new curriculum also focused more on active learning than on a didactic approach, and booster sessions were added to reinforce skills learned in prior years. Pilots of the new program were tested in 14 cities in 2001 prior to its implementation in 2002-2003. (At the time of this publication, the revised program curriculum has not been evaluated.)"
