To assess the theoretical and practical knowledge about emergency contraception (EC) among family-planning (FP) providers in Ghana and to examine the association between FP providers' theoretical and practical knowledge.

Data on 600 FP providers were collected through a census of facilities offering FP services in Kumasi, Ghana, in 2008. Nested linear multivariate regression analysis was used to identify sociodemographic, facility-related, and work-related variables associated with FP providers' theoretical and practical knowledge about EC.

On average, FP providers gave 4.1 correct answers to the 11 questions assessing theoretical knowledge and 5.6 correct answers to the 8 questions assessing their practical ability to provide EC. The FP providers seemed to learn provision-related aspects through practice without having a particularly good theoretical knowledge on EC as a contraceptive method. The health sector in which FP providers worked, their education and having received EC-specific training, the number of services offered, and the number of women seen during a week were all significant correlates of both theoretical and practical knowledge about EC. The 2 knowledge domains were significantly and positively associated.

There is need to improve knowledge about EC among FP providers in Ghana through in-service training.
