Staffing??

We sent in our homestudy on two little siblings. There were 15 other families who sent in theirs also. We were contacted after the CW received our homestudy through email stating "I will contact you if we are interested in having you participate in a staffing". I know what a staffing is, but how long until people are contacted. It has been 1 week. Is there an average wait time? Do most CW atleast notifiy you when you are not chosen? Our CW is not helpful at all. And acts like she just wants us to foster and not adopt, I know our area is short on foster homes. I think she is afraid that once we adopt we will be done fostering. It is so frustrating to not have someone to ask these type of questions. Thank you. __________________
