Frequently asked questions

What is the Bishop score?

A pre-induction cervical scoring system (0–13) that predicts likelihood of successful labor induction and need for cervical ripening.

What score favors induction?

Bishop ≥ 8 (some use ≥ 6 in multiparous patients) — labor induction is likely successful without ripening agents.

What is a modified Bishop score?

Several modifications exist (e.g., Burnett, simplified Bishop using dilation, effacement, station only). The original 5-component score remains most common.

What should be done if Bishop is low?

Use cervical ripening (prostaglandins, mechanical methods) before initiating active labor induction with oxytocin.
