The details below are obtained from the CQC CRB Guidance 2011 – Page 16, Question 24

“Students over 18 years of age undertaking placements in health or social care settings will require an enhanced CRB check and ISA registration where the placement involves children or vulnerable adults and the contact is frequent, intensive or overnight.

The check may be obtained by the educational establishment at the start of the course, but the health or social care provider should obtain written confirmation that the student has had a satisfactory CRB check at an enhanced level at the start of the course and checks against the Children’s and/or Adults Barred list.

As above, the provider is ultimately responsible for the safety and wellbeing of people in their care and should assure themselves that the checks are satisfactory.

Students under 18 years of age on placements such as work experience do not require a CRB check on the basis that the role will not be taking the place of an existing care worker and will be supervised.”
