In response to some questions we’ve received about our School Library Journal article and our future plans for school library research:
The results reported in this article represent the first part of a larger study we are conducting to look at the relationship between school librarian staffing and achievement scores. Our next step is to do a more in-depth analysis of Colorado schools, where we have access to staffing and achievement test data at the building level (the data used for our SLJ article were at the state level). Look for a report of the results in the coming months. We encourage others to pursue this type of research in their state/region.
