This study aims at identifying the effectiveness of the staff working at the clinics of the Jordanian Association for Family Planning and Protection (JAFPP); it achieves this by identifying the clients' satisfaction with the staff€™s ability to render reproductive health services. The study also aims to identify the relationship between the demographic, economic and social factors and the satisfaction of the clients with the staff. To achieve the goals of the study, a representative stratified random sample of 50% of the JAFPP clinics from each of the 3 regions of the kingdom has been randomly selected. For 3 days, all the clients who visited those clinics were interviewed. In addition, all the staff members of all of the JAFPP 19 clinics were interviewed, so that the sample's size was (541) clients. The study used the descriptive method, and the questionnaire as a mean of data collection, and the descriptive ways for the data analysis.  The major findings of the study are: - The clients are satisfied with the clincs€™ staff€™s competence and attitude, but they think that its number is not sufficient. They also believe that the female staff and the services€™ prices are the major factors that distinguish JAFPP from other similar organizations.  - The one way ANNOVA test, which was followed by Duncan test, showed that there is a relation between some the economic, social and demographic factors (educational level, age, work, marital status, monthly income, insurance) and the satisfaction of the clients with the staff and the services provided. Finally, the researchers suggested a number of recommendations based on the study results, the most important of which are: JAFPP should concentrate more on the role that the social worker is currently playing in giving quality and quantity advice. JAFPP should also improve its internal regulations, especially regarding incentives and salaries, along with the clincs' working times. It should increase the number of the clincs' staff as well.
