Hallett and Chapman were already informal pro bono advisors to the national Annenberg Challenge, and over the course of the following year they met repeatedly at Brown University with other Annenberg advisors and worked to ensure that Chicago would be one of the first cities selected to receive a grant......

.....An August 2003 final technical report of the Chicago Annenberg Research Project by the Consortium on Chicago School Research said that while "student achievement improved across Annenberg Challenge schools as it did across the Chicago Public School system as a whole, results suggest that among the schools it supported, the Challenge had little impact on school improvement and student outcomes, with no statistically significant differences between Annenberg and non-Annenberg schools in rates of achievement gain, classroom behavior, student self-efficacy, and social competence."
