This technical report describes the process of development and piloting of reading comprehension measures that are appropriate for seventh-grade students as part of an online progress screening and monitoring assessment system, http://easycbm.com. Each measure consists of an original fictional story of approximately 1,600 to 1,900 words with 20 multiple choice questions assessing students' literal, inferential, and evaluative comprehension skills. Three answer options are provided for each question: correct, near correct, and far correct. All measures were piloted with seventh-grade students whose teachers responded to the pilot invitation on the official easyCBM website. The data were analyzed using one parameter Item Response Theory (IRT) modeling. Complete results of the pilot testing are presented and discussed. Appended are: (1) Item Specifications for MC Comprehension; (2) Suggested Guidelines for ordering items for test pull and test form development; and (3) Item Ordering Tables for Seventh Grade. (Contains 19 tables.)
