When to use
Predict success of induction and need for cervical ripening.
How it works
Points for dilation, effacement, station, consistency and position. ≥ 8 favourable; ≤ 6 often needs ripening.
Key points
- Higher scores predict successful vaginal delivery.
- Low scores prompt cervical ripening agents.
- Station and dilation carry the most weight.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Dilation | Closed (0) |
|---|---|
| Effacement | 0–30% (0) |
| Station | −3 (0) |
| Consistency | Firm (0) |
| Position | Posterior (0) |
→Bishop0/13
- Interpretation：Unfavourable — consider cervical ripening
| Dilation | ≥ 5 cm (3) |
|---|---|
| Effacement | ≥ 80% (3) |
| Station | +1/+2 (3) |
| Consistency | Soft (2) |
| Position | Anterior (2) |
→Bishop13/13
- Interpretation：Favourable — induction likely to succeed

- Inputs: Dilation Closed (0), Effacement 0–30% (0), Station −3 (0), Consistency Firm (0), Position Posterior (0) → Result: Bishop 0 /13（Interpretation: Unfavourable — consider cervical ripening） Inputs: Dilation ≥ 5 cm (3), Effacement ≥ 80% (3), Station +1/+2 (3), Consistency Soft (2), Position Anterior (2) → Result: Bishop 13 /13（Interpretation: Favourable — induction likely to succeed）
