The Educators Evaluating the Quality of Instructional Products (EQuIP) Rubric for science is a new tool for science educators that provides criteria by which to examine the alignment and overall quality of lessons and units with respect to the "Next Generation Science Standards" ("NGSS"). The rubric criteria are divided into three categories: alignment to the "NGSS", instructional supports, and monitoring student progress. The purposes of the rubric and review process are to: (1) review existing lessons and units to determine what revisions are needed; (2) provide constructive, criterion-based feedback and suggestions for improvement to developers; (3) identify exemplars/models for teachers' use within and across states; and (4) inform the development of new lessons and units. The rubric is currently being used more to review existing lessons and determine what revisions are needed, provide feedback, and inform the development of new lessons than it is to identify exemplars. But as more materials are created and revised, the rubric will be increasingly used for this purpose. A sample of a rubric section used to assess alignment to the "NGSS" is presented in this article. The author has had the privilege of helping coordinate the development of the EQuIP rubric for science--which included working with state teams, teacher focus groups, the National Science Teachers Association, and others--and of using the tool with many educators since it was released in April and updated this fall. In this article she shares some reflections on these experiences and on the tool itself.
