The U.S. Department of Education released an interim report presenting the impacts of Reading First on classroom reading instruction and student reading comprehension during the 2004–05 and 2005–06 school years. The study found that Reading First did have positive, statistically significant impacts on the total class time spent on the five essential components of reading instruction promoted by the program. The study also found that, on average across the 18 study sites, Reading First did not have statistically significant impacts on student reading comprehension test scores in grades 1–3.
