The guidance provides examples of more than 50 matters reserved for the board, from approving policies and budgets to drawing up health and safety policies and settling litigation.
It covers areas such as strategy, contracts, financial documents, communications, drawing up policies and handling litigation.
Louise Thomson, head of policy for not-for-profit organisations at the ICSA, said: “An agreed list of matters reserved for the board should be combined with clear procedures for monitoring those functions delegated to others, to ensure that trustees maintain overall control of the direction and performance of the charity.”
The ICSA has also released a sample skills audit for charity trustees. The audit includes a form for trustees to fill in to help them to identify skills and experience useful to the charity, and another where the charity can list its aims and needs to help it ensure it has trustees able to meet them all.
The guidance and audit can be downloaded from the ICSA website.
