To assist members with budget-setting, we commissioned a group of our most experienced expert practitioners – ISBL Fellows and/or accredited school resource management advisers (SRMAs)\* – to develop a set of budget assumptions using the most current intelligence.

This latest version of the guidance was updated in March 2026.

We hope you find this guidance helpful, and as ever, we are always interested to hear alternative perspectives.
