Induction is generally attempted when a mother has a favorable Bishop's score.  A score of five or less is said to be "unfavorable." If induction is indicated, the mother would be a candidate for a cervical ripening agent. These are usually introduced one or two nights before the planned induction.  A score of eight or nine would indicate that the cervix was very ripe and induction would have a high probability of being successful.

Your care provider can assist you in understanding and interpreting your Bishop's Score.
