Hello - I was a sw and tm mgr of a Fostering & Adoption panel and chaired Fostering panels until it had to be done by an independent person, so then I was the panel advisor (the sort in interface between the chair and the dept.)
I think much depends on the way different LAs run their panels. For the LA I worked for for 25 years, the practice was good. We used to send out letters explaining to applicants that it would be a multi disciplinary panel (someone for Health, Education, Independent person, fostering sw, children's sw and a young person who had been fostered. In addition there may be a student observing panel.
As someone has already said, going into a room with up to a dozen strangers is very daunting and it doesn't matter that they all smile and introduce thenselves, it will still feel very alien. We used to tell applicants in the letter than panel expected them to be nervous. There are no trick questions. Beofre you go in the panel chair should organise who is going to ask you what (IYSWIM) it's not meant to be aQ and A session but inevitable it turns out that way. If you don't understand what someone is asking say so, and take your time, no need to rush, and remember that foster carers are like gold dust to LAs so they want you as much as you want to foster.
We used to ask the applicts to wait for a few minutes and had a quick discussion to ensure all panel members werein agreement and call them back in to say they were approved! Well strictly speaking the LA I worked in could only recommend approval as the final decision had to be ratified by the Agency Decision Maker (A snr mgr) but that was a formality and then a couple of weeks later they got the letter confirming approval.
Mind I know all panels don't work like that I worked independently for a few years after I retired and was interviewed and offered the job on Independent Chair of theFostering Panel for a neighbouring LA (though much more urban) I had worked in a Shire county. They invited me to observe their panel and I was horrified.......the chair just decided everything - she/he is meant to ensure the smooth running of the panel - the panel members could have bee cardboard cut outs and the legal adviser came in late and immediately got out a large submarine roll and began eating it, spilling bits everywhere! Very often applicants didn't come to panel (that's what used to happen in the old days) but I couldn't believe it was still happening. After that I told the LA I didn't want the job thank you. They asked why and I sent a 5 page letter telling them what was wrong with their panel! The snr mngr phoned me and agreed but asked if I could "put things right" and offered me an extra £1 per hour (on top of my fee)...............needless to say I refused. (Oh just remembered the panel went on from 9.30 am to 4.00 without a break for lunch but there were some mince pies (which I hate!) and that was it, so I drove home with a massive headache!
I just hope your LA is a good one. Are you a single applicant and do you have a child or children of your own. If you don't then there may well be some concern that you don't have experience of children, but maybe you have worked with children or something of that sort.
Good luck and try not to worry - they are all ordinary mortals like you and me!! Oh and the other thing is panels are nearly always running late so you may have to wait for a while, which is not good but that's the way it often is.
