Schools now have a legal duty under "Safeguarding Children and Safer Recruitment in Education" to ensure that any staff they engage, including agency staff, have been properly vetted.
At TimePlan we make this easy for schools. Before we send a TimePlan Teacher or Support Staff to your school you will receive a Photo ID Security email giving the individual’s details and the vetting checks that we have carried out. These can be kept to fulfil OFSTED requirements on Child Protection. Download an example (pdf).
