Bishops Score

Before considering labour induction, you can determine your chances of a successful induction by scoring yourself using the Bishops Score table, below.

A lower score can mean induction may be more difficult, longer, and will most likely be harder on you and your baby.

The higher the score, the more favorable the cervix. Clinical trials showing a score of 6-7 or more were associated with successful inductions, but most agree that a score of 9 is preferable.
