This study investigated the perceptions of teachers of grades three, four, and five regarding differentiated instruction in conjunction with Standards-Based Report Card as aligned to the Common Core State Standards. The purpose of this study was specifically seeking teacher perceptions on how these phenomenon interact, as well as teacher to parent communication, student awareness of standards, and reassessment practices. The sample (n = 140) consisted of regular education teachers, grades three, four, and five from districts in both Illinois and Missouri. These districts used a Standards-Based Report Card at one or more of these intermediate grade levels. The participants completed a survey designed to determine teacher perceptions of the effect of differentiated instruction on the Standards-Based Report Card in conjunction with the Common Core State Standards. This survey was developed to answer the six research questions. The researcher analyzed the data descriptively and inferentially. The researcher concluded that districts need more training and need to promote teacher buy-in. The descriptive results demonstrated teacher perceptions about communication, student awareness, and reassessment. Overall, teachers do not perceive that they are communicating more due to the Standards-Based Report Card. Teachers tend to agree that students are aware of their progress as a result of the Standards-Based Report Card and that they are reassessing in math and ELA. The researcher concluded the study by suggesting recommendations for further research in the area of Standards-Based Report Cards at the intermediate level.
