From NSPCC:
Self-declaration doesn’t replace the need for a DBS disclosure check for eligible roles, but can provide additional information that a DBS check will not.
Self-declaration can be part of an organisation’s safer recruitment process. It involves requiring an individual to provide information to be used as part of a decision on their suitability for a particular role with children.
It is recommended good practice to use a separate self-declaration form rather than embed self-declaration questions within their overall application form.
We have developed 2 self-declarations forms. One for roles that are eligible for DBS checks and one for roles that are not eligible.
