Bishop score calculator
Tally the five cervical-exam findings — dilation, effacement, fetal station, consistency, and position — for the published Bishop score and its cited favourability band. A scoring aid, not a management decision, and nothing you enter leaves your device.
Pick the finding from each cervical-exam row. Each parameter contributes a fixed number of points; the total runs 0–13.

Bishop score
Pick a finding in all five rows to see the total and its cited favourability band.
In the original 1964 paper, a score of 9 or more was predictive of a successful induction; a score of 5 or below indicated labour was unlikely to begin in the next few days. A modified Bishop score replaces effacement with measured cervical length (maximum 12), where a score of 5 or more is considered favourable. Thresholds vary by source and by parity.
Scoring aid, not a diagnosis or a management decision. This tool only tallies the cervical-exam findings you enter against the published Bishop score and reports a cited favourability band. It does not recommend inducing, waiting, or ripening, and it never names or doses any cervical-ripening agent. Thresholds vary by source and by parity. The decision rests with the attending obstetrician.

How the Bishop score works
The Bishop score sums five cervical-exam findings — dilation, effacement, fetal station, consistency, and position — into a 0–13 total that describes how favourable the cervix is. A higher score (traditionally above 8) describes a favourable cervix; a low score (≤4) describes an unfavourable one. The number describes the cervix; it does not decide whether or how to induce — that is the obstetrician's call.
A common variant, the modified Bishop score, replaces effacement with measured cervical length (maximum 12), where 5 or more is considered favourable. The tool shows the traditional score and notes the modified variant; thresholds vary by source and by parity.
Many units still tally this on a paper proforma. If you run an obstetric practice, our OB-GYN clinic workflow page explains how Avinya Plus's template builder and formula engine let you build the Bishop parameters into a labour or antenatal form, total them automatically, and keep the favourability band on the note. Avinya Plus ships no pre-built obstetric instrument — you configure it; the arithmetic and banding are the engine's.
Frequently asked questions
- How is the Bishop score calculated?
- Five cervical findings — dilation, effacement, fetal station, consistency, and position — are each given a fixed number of points and summed to a maximum of 13. Dilation, effacement, and station score 0–3; consistency and position score 0–2.
- What is a favourable Bishop score?
- Per the cited source, a total above 8 describes a favourable cervix; the original 1964 paper used 9 or more as predictive of successful induction. A score of 4 or below describes an unfavourable cervix. Thresholds vary by source and by parity.
- What is the modified Bishop score?
- A common variant replaces effacement with measured cervical length (maximum 12), where 5 or more is considered favourable. The tool shows the traditional score and notes the modified variant.
- Does the tool decide whether to induce?
- No. It reports the published score and its cited favourability band only. It does not recommend inducing, waiting, or ripening, and never names or doses any agent — that decision rests with the attending obstetrician.
- Does any of the data I enter leave my browser?
- No. The scoring runs entirely in your browser; nothing you enter is sent to a server or stored. The print option produces a clean worksheet you can save as a PDF.

The five-parameter point table and favourability cut-points are reproduced from StatPearls (NBK470368). A modified Bishop score replaces effacement with cervical length (max 12, favourable ≥5). Thresholds vary by source and parity; the score is a published predictive band, not a recommendation. Reviewed against the source on 2026-06-29. Verify against the current RCOG / ACOG / FOGSI / national guideline.

In Avinya Plus you can build the Bishop parameters into a labour or antenatal template, total them automatically, and keep the favourability band on the note. See it on a quick demo.
