Hi welcome to the site.
Addressing gaps and shortfalls is a way to ensure best practice is at the centre of your professional management. Consider how these are currently looked at in the setting eg. own & colleagues training, safeguarding, child protection, information sharing, when are the contents of the setting's policies and procedures examined and how are action plans used.
There is good reading on page 87 of the
level 5 HS and child services handbook - search in the preview on amazon for the word
'gaps'
