People who have been convicted of certain offences are disqualified by law from providing childcare.
You must make sure that you're not recruiting, or redeploying, someone who's disqualified into a role regulated by the childcare disqualification regulations. It's an offence if you knowingly do so.
Which offences disqualify someone?
The list of offences and orders that result in disqualification is included in guidance published by the DfE (see the appendices for a full list).
Disqualification by association no longer applies in schools
Previously, people working in schools could be disqualified by association if they lived with someone who was disqualified. Since 31 August 2018, this no longer applies to schools.
You shouldn't ask staff questions about cautions or convictions of someone living or working in their household.
