Bishop Score Calculator
Labor induction is an important decision during pregnancy, and healthcare professionals rely on specific clinical indicators to estimate how ready the cervix is for labor. One of the most widely used assessment tools for this purpose is the Bishop Score. Understanding this score can help expectant mothers and medical learners gain insight into labor readiness.
Our Bishop Score Calculator is a simple and reliable online tool designed to calculate the Bishop Score instantly based on key cervical and fetal factors. By selecting values from clearly defined options, users can quickly see the total score, its interpretation, and the likelihood of successful labor induction.
This calculator is especially useful for educational purposes, exam preparation, and general awareness, offering a clear breakdown without complex medical jargon.
What Is the Bishop Score?
The Bishop Score is a clinical scoring system used to evaluate the condition of the cervix before labor induction. It helps determine whether induction is likely to succeed or whether the cervix is still unfavorable.
The score is based on five clinical parameters, each contributing a certain number of points. The total score typically ranges from 0 to 13, with higher scores indicating greater readiness for labor.
Parameters Used in the Bishop Score Calculator
This Bishop Score Calculator evaluates the following five components:
1. Cervical Dilation
Measures how open the cervix is, expressed in centimeters. Greater dilation increases the score.
2. Cervical Effacement
Indicates how thin the cervix has become, shown as a percentage. A higher percentage means a higher score.
3. Fetal Station
Describes the position of the baby’s head in relation to the pelvis. A lower station suggests labor readiness.
4. Cervical Consistency
Refers to how firm or soft the cervix feels. A softer cervix is more favorable.
5. Cervical Position
Shows whether the cervix is positioned posteriorly, mid-position, or anteriorly. An anterior position earns more points.
Each of these factors contributes to the final Bishop Score.

Example of a Bishop Score Calculation
Selected Inputs:
- Cervical Dilation: 3–4 cm
- Cervical Effacement: 60–70%
- Fetal Station: −1 or 0
- Cervical Consistency: Soft
- Cervical Position: Anterior
Result:
- Bishop Score: 9 / 13
- Interpretation: Favorable cervix
- Labor Likelihood: Induction likely to be successful
This result suggests that the cervix is well-prepared for labor induction.
Understanding Bishop Score Results
The calculator provides clear interpretations based on the total score:
Score 0–5: Unfavorable Cervix
- Cervix is not ready for labor
- Induction is unlikely to be successful
- Cervical ripening may be required
Score 6–8: Moderately Favorable Cervix
- Some readiness for labor
- Induction may be considered
- Success depends on clinical judgment
Score 9 or Above: Favorable Cervix
- Cervix is ready for labor
- High likelihood of successful induction
- Often associated with better outcomes
