Young People Now understands that the role of personal advisers is likely to remain part of the Government's plans for future services outlined in its youth green paper, but their remit and who they will be accountable to is under review.
Carolyn Caldwell, chief executive of the association, hinted that Connexions could be adapted to fit in with a more integrated system of services, although she saw the current organisation as a solid base to build on.
She would not be drawn on possible reforms, but acknowledged that the organisation was in a "critical phase".
"The Government is looking for better integration and co-ordination of services and wants to simplify the multiple funding streams and fragmented accountability," she said. "Connexions, already a recognised partnership brand, is a solid base on which to build such integration."
The Institute of Career Guidance, which has a high percentage of members who are unhappy with the quality of careers guidance within Connexions, is pinning its hopes on a reform of the service.
Liam Duffy, president of the institute, said: "The forthcoming youth green paper offers the chance to address this issue and it is our hope that the Government takes the opportunity to do so." He added that the institute would be consulting members following the publication of the green paper and would formulate a response in due course.
The green paper is expected to be published in November.
