The purpose of this technical report is to document the piloting and scaling of new easyCBM mathematics test items aligned with the Common Core State Standards (CCSS) and to describe the process used to revise and supplement the 2012 research version easyCBM CCSS math tests in Grades 6-8. For all operational 2012 research version test forms (10 progress monitoring and 3 benchmark) five items were selected for removal based on statistics indicating less than optimal functioning. Items from the current pilot were used to replace the five selected items. Additionally, five items previously written to the National Council of Teachers of Mathematics Focal Point Standards, but rated as aligned with the CCSS, were added to each form. Finally, an additional fifteen items were included in benchmark tests to link forms across grades, in preparation for future vertical scaling of tests. Common items were also included between benchmark forms within each grade for planned horizontal scaling analyses.
