Bishop Score

Bishop EH. Pelvic scoring for elective induction. Scored cervical dilation, effacement, station, consistency, and position; a higher total predicted a shorter interval to delivery and a successful elective induction.

ACOG Practice Bulletin 107 (induction of labour) uses the Bishop score to describe cervical favourability: a score ≤ 6 is generally considered unfavourable and supports cervical ripening; ≥ 8 predicts a vaginal-delivery likelihood similar to spontaneous labour.
