Elementary Teacher Librarians in the Tacoma Public Schools currently do not have an assessment framework specific to libraries to evaluate student growth and learning that is tied to TPS library learning targets and current AASL standards. I followed best practices to create customizable a pre- and post-survey tool using a qualitative rating scale using Microsoft Forms that librarians can administer to students, which allow for the collection of quantifiable and qualitatively rich data. Data gathered can be used to measure student growth, identify reteaching opportunities, and to improve librarians’ professional practice. Benefits extend to students, teachers, and administrators as well.
