The waiting, what is normal for the process?

We decided in July that we wanted to be involved with foster parent/adoption program. We finished up the PS-MAPP classes in November. We are assigned a licensing worker. She set up appointment for her to come to our home and she no showed. We called and rescheduled. She came over and took all our paperwork and no I didn't make copies. We thought she would go over it with us, but she just took it and said she would send me an email with more information. I have no correspondence from her since the first week of December. I spoke to a few others in our class and they are having similar issues. I sent her an email yesterday, but no response. I don't want to make waves and get blacklisted or something but I really think if I don't keep on them it will be months. I keep hearing about the desperate need for help but they don't seem to think so... It would also have been nice to let us know of ways we could help out while we are waiting for the paperwork to be processed. So the question is this normal? Does it take months after completion of the class to hear back? We still have to have our home inspection and go over our preference for children.... Some of us are wondering is there some psychological game or is there a reason for the waiting?
