To help prepare students for Next-Generation Writing Assessments, Rainbow developed content for new Test Writing Chapters for Strategies for Writers ©2015, Grades 2–8. Working in InCopy templates, all content was developed using a K4 workflow. Rainbow handled the literature search for permissioned Text Stimuli as well as developed new content for commissioned Text Stimuli. Our team also handled the editorial development of the Student Edition, Teacher Edition, and Optional Revising Lessons (ORL). Finally, all content was aligned and correlated to the Common Core State Standards.
