Partnership for Assessment of Readiness for College and Careers (PARCC) Operational Study 4 Component 3 was designed to compare performance on PARCC mathematics field-test items for grade 3 taken with and without a drawing tool. For the 2016 testing window, five field-test items were selected to have the directions edited to allow students to provide a drawing as part of responses and directions on how to include a drawing. For those students, using the drawing tool was optional, and a drawing was not required for earning full credit. The standard variant of these items did not include the directions or the tool option. Both variants were included in the embedded online field-test forms to determine if there was a significant difference in performance. If no significant differences were found, then there would be evidence to allow the inclusion of the drawing response interaction on existing items. All mathematics items available to be embedded into the Spring 2016 forms were reviewed and approved by PARCC. No new items were created for this study, only variant items with modified direction lines. This report summarizes the quantitative and qualitative evidence bearing on the comparability of the study items administered with and without a drawing tool.
