Figure 1. was taken directly from Bishop's research paper to show how each category is scored (Bishop 1964). Dilation, for example, is assessed based on the amount of centimeters dilated by the woman. For example, 0 cm produces a score of 0, 1-2 cm produces a score of 1, and so on. The possible scoring range from this tool is 0 to 13 points. The higher the score, the closer the mother is to the end of her pregnancy. Bishop says his experience has convinced him that the safest induction is achieved when the pelvic score is 9 or higher. He goes on to describe that no induction failures have occurred and that the average duration of labor is less than 4 hours when induction is performed on a woman with a pelvic score of 9 or
