From the Colorado Library Research Service:
Every year, we conduct a survey of Colorado public school libraries. The results of this survey, which include information about library instruction strategies, collections, web presence, staffing, usage, and budgets, help administrators, school library staff, and other stakeholders with planning and evaluation. These results are also used to market and advocate for school libraries; for example, earlier this year we published a school library infographic that shows the impact of school libraries on academic achievement.

The School Library Profiles developed by the Library Research Service are meant to be used as a comparative tool for school libraries in Colorado. The results represent data received from school libraries that completed the 2012 Colorado School Library Survey. Profiles for each participating school compare individual school data with averages for schools with similar grade level and enrollment ranges. Please note that since all data were derived from responses to the survey, schools that did not respond to the survey are not represented in the Profiles.
