The Improvement and Development Agency is to introduce the guide as part of its Connecting With Communities tool kit, which offers advice on all areas of communication.
According to the CPA section's author, IDeA associate director and MD of agency MPC Marina Pirotta, the guide will echo advice given at a recent Local Government Association conference on the issue (PRWeek, 11 October).
This includes urging councils to keep local media, organisations and council staff updated on the assessment process, rather than reacting when the final CPA results are announced in December.
It will also highlight warnings not to criticise inspectors if results are unfavourable.
The guide is available on www.idea.gov.uk/knowledge from early November.
