I couldn't find any really good assessments for theme, so I created this one. I'm also including a one-page sheet that lists 12 common text themes for you to use to teach/review theme. On the test, students will read a short passage and then circle the theme (out of four choices) that best fits the passage. There are 12 passages and questions. Answer key is included. Hope this helps you assess your students' understanding of theme!
