Achievement Effects of Four Early Elementary School Math Curricula

NCEE 2009-4052
February 2009

Next Steps for the Study

Another 71 schools joined the study during the 2007-2008 school year (the year after the 39 schools examined in this report joined), and curriculum implementation occurred in both the first and second grades in all participating schools. A follow-up report is planned that will present results based on all 110 schools participating in the evaluation, and for both the first and second grades. The study also is supporting curriculum implementation and data collection during the 2008-2009 school year in a subset of schools, in which implementation will be expanded to the third grade. A third report is planned that will present those results.
