We hesitate to suggest that this scale would easily transfer to report cards because report card grades are based on multiple pieces of data. The cut scores were determined through a process with consideration of several factors (i.e. analyzation of patterns created by the cut scores across several schools, comparison with MSP data for the same classrooms, etc.).
Additionally, Data Dashboard (DDS) and its leveling system reflect the score on a specific test of grade level standards - not an overall performance for a student or an indicator of above standard performance (a score of 4).
