Hi Shaz - please try not to feel nervous about panel. I am a retired sw and tm mgr in fostering and adoption (30 years experience). I think one of the worst things for applicants is walking into a room with approx 9/10 strangers. Panels used to be much smaller but the regs now mean that panels have to multi-disciplinary, so there will be the chair, a clerk taking notes, a medical member (HV or similar) an education rep, an ind member (county councillor) family plct social worker, children & family social worker, and panel advisor, a young person who has been fostered.
Panels do realise that applicants will be nervous and make allowances for this. If you have a positive recommendation from your assessor, you will be fine. The panel advisor should pick up anything that they think is missing from the Form F submitted by the assessor, or anything that isn't clear and discuss this with the assesssor. Sometimes assessors have to re-visit families. If this works as it should, it means that applicants are not asked to clarify any issues in the form. No-one is trying to trip you up - you will probably be asked initially about your prep group and whether anything stuck out for you etc. Then the various members will ask anything relevant to their profession, but only things that are in the form F. Don't forget that foster carers are gold dust to the LA (assume you are going to LA) if you are going to an IFA panel then I am not so sure how these work, as I have only worked for a LA.
I note that your offer appears to be a child under 6 (with disabilities) on a permanent basis. To be honest I always worry about new carers taking on permanent placements, not that they are not needed, quite the reverse, but I always think it best to start short term so that you get used to having LA children in your home. The most successful way of taking a permanent placement is to foster a child on a short term basis and if you are sure that it is right for you and the child, then to convert the placement to permanence. These placements are the most successful.
Anyway good luck and best wishes.
