Our Work in Action
Addressing Student Needs
Louisiana sought to provide districts and schools with a comprehensive assessment system to monitor student learning and address student needs. Working collaboratively, WestEd developed content for the State’s diagnostic assessments for English/language arts and mathematics.
The diagnostic assessments—key components of Louisiana’s LEAP 360 assessment system—were designed to give educators a general sense of student readiness for grade-level content and indicate the level of support students might need as they proceed through the curriculum.
In addition to the assessment content, WestEd developed scoring materials to guide teacher grading of student responses.
In Florida, we assisted the Florida Joint Center for Citizenship (FJCC) at the Lou Frey Institute to develop the capacity to train Florida educators in item-writing practices through workshops designed for social studies teachers, curriculum coordinators, and FJCC staff. As a result, the FJCC expanded their existing item banks on their assessment preparation website and teacher resource websites.
We worked with our friends at WestEd to support practice assessment development for civics educators across the state of Florida. WestEd was instrumental in supporting this collaboration with teachers and their work with us remains impactful to this day.
