2Acknowledgements and DedicationI would like to thank and acknowledge Dr. Amy Danley for her guidance, support, andencouragement throughout the dissertation journey. I couldn’t have asked for a better coach, andI’m grateful for what I have learned throughout our collaboration. Dr. Danley made the processjoyful. I’m also grateful for Dr. Elisabeth Bennet and the constructive feedback she providedalong the way. This study is better because of their wise counsel.I would also like to acknowledge Dr. Lee Ann Jung, who served as an expert third readerand participant in my dissertation defense. I have a vivid memory of a car ride through the busystreets of São Paulo, where knowing the complexities I was living through in my own role as aMiddle School Principal, Dr. Jung provided inspiration and encouragement regarding mydoctoral aspirations. Similarly, I am deeply appreciative for the statistical assistance from Dr.Tom Gollery; I’m continually amazed by his mathematical prowess. Likewise, I’m grateful forDr. Jessica Parker’s guidance.This dissertation is dedicated to two individuals: Susan Butler and my husband. SusanButler is one of the most amazing and talented educators and leaders I have ever had theprivilege to count as a colleague. Her daily support provided the space for me to complete thisstudy while at the same time managing the demands of running a middle school. Likewise, I amgrateful for my husband’s support and patience, particularly through long nights of reading andweekends dedicated to writing. This dissertation is as much theirs as it is mine.

3AbstractSchools and districts worldwide are transitioning from traditional grading models to standardsbased grading (SBG) without fully understanding the effects of these models on studentachievement. The purpose of this nonexperimental correlational study was to assess the degree towhich grades assigned on a traditional report card and a standards-based report cardmathematically associated with and predicted standardized assessment scoring as measured onthe Northwest Evaluation Association’s Measures for Academic Growth (NWEA-MAP) in theareas of mathematics and language arts for middle school students. Participants were comprisedof Grade 6 through Grade 8 students in a leading American school in the Middle East that hadundergone a shift from traditional grading towards standards-based grading. Data utilizedincluded traditional grades, standards-based grades, and performance on the NWEA-MAPassessment for a span of 11 years. Results suggest that grades reported through a SBG reportcard more accurately communicate student learning results than a traditional (A-F) report card.The researcher found a stronger mathematical association and predictive effect between SBG andNWEA-MAP scores than traditional grading. Knowledge generated will inform schoolsconsidering standards-based grading.Keywords: grades, grading, grading practices, standards-based grading, standards-basedreporting, NWEA, assessment correlation, and implementing standards-based grading.
