You need to understand what concurrent planning is all about before you start making assumptions based on a snippet you heard in a radio programme.
Concurrent planning is a scheme where children who have been removed from the care of their parents (not wrongly removed of course) but removed for their safety and protection, are placed with prospective adoptors rather than short term foster carers. This is NOT to be confused with Atlantis's outlandish claims that children are placed with adoptors when they are first removed and are somehow sneakily adopted.
The prospective adoptors are made fully aware that the aim of the SSD in these cases is to carry out extensive assessments on the parents and to attempt wherever possible to reunite the child with the parents. Short term foster carers already know that this is what happens and do not in any event want to care for a child on a permanent basis, hence the term short term carer.
Prospective adoptors involved in concurrent planning have to sign up to fully co-operate with the local authority's aim to reunite the child and parents. There will be extensive supervised contact between the child and parents (which is always the case bt something short term foster carers are used to)and the prospective adoptors will need to co-operate with the birth parents as well as all professionals involved in every respect.
IF at the end of the assessments it is decided by the courts that the child can be returned to the parents, then this is what happens, sometimes without any order being made, sometimes a Supervision Order and sometimes a Care Order, both of which can be revoked at a later date if appropriate.
IF it is decided by the courts that the child cannot be returned to the care of the parents, then the court will make a Placement Order (used to be called Freeing for Adoption) and the child remains with the prospective adoptors who in due course are entitled to make an application to adopt the child.
The thinking behind this scheme is to prevent the trauma of moving the child from foster carer to adoptor (unless the child is returned home) and so enabling secure attachments to be made with very obvious benefits to the child.
It is a difficult concept for prospective adoptors who are longing for their own child, and many will not want to be part of this scheme, or indeed will be suitable for the scheme. They run the risk of building secure attachments to a baby or child, only for the child to be removed and returned to the parents. I think this is wholly right if the child can be safe and protected by the parents, but it does not mean that the prospective adoptors will not suffer in the process. However this is all about the needs of the child rather than the adults, be they parents or prospective adoptors.
SO JH I don't know what you heard (but knowing you you will have got it round your neck and will now be busy using it as grist to the mill to support your hypothesis) and quite how you can determine the social class of someone by their voice on a radio is beyond me. The radio programme was probably something similar to the DM reports.
It is absolutely nothing to do with the prospective adoptors as to whether the parents are "allowed" to have their children back. This is the decision of the courts and they were probably using the term "allowed" to mean exactly that. You will distort anything you read or hear to support your nonsensical hypothesis.
I hope anyone reading this can now be convinced about the scheme and that it's aim is to protect children from being moved from place to place (incidentally this is something that you have complained about JH many times) so you should welcome such a scheme.
