Based on the graph, a score of 5 appears to be the cut score that would best predict whether a copy editor's performance is rated as acceptable or unacceptable. At this score, the proportion of acceptable copy editors who score above the cut score is much higher than the proportion of unacceptable copy editors who score above the cut score. This suggests that a score of 5 is a good threshold for identifying potentially successful copy editors.
