Bishop Score Induction Calculator

Summary

Select five cervical exam parameters to calculate the Bishop score and assess labor induction readiness.

How it works

1. Select the current value for cervical dilation (cm).
2. Select effacement percentage — how much the cervix has thinned.
3. Select fetal station relative to the ischial spines (-3 to +2).
4. Select cervical consistency (firm, medium, or soft).
5. Select cervical position (posterior, mid, or anterior).
6. The calculator sums all five sub-scores (0–13) and displays a favorability rating with clinical guidance.

Use cases

• Obstetric providers assessing cervical readiness before scheduling labor induction.
• Medical students and residents learning how each parameter contributes to the total score.
• Nursing staff verifying Bishop score calculations at the bedside.
• Determining whether cervical ripening agents (e.g., prostaglandins, Foley balloon) are indicated before oxytocin.
• Comparing serial exams to track cervical change over time.
• Educational reference for understanding the clinical criteria behind each sub-score.
