[holding answer 1 March 2007]: Disclosures are primarily designed to be used by an employer at the point of recruitment for a particular position. Ultimately it is for each employer and not the CRB to decide whether a fresh disclosure should be applied for, bearing in mind their legal and other responsibilities and subject to any statutory requirements. There are a number of reasons why an employer may not wish to accept a disclosure that has been processed for a previous employment position, including:
The disclosure may not be at the right level (there are two different levels of CRB check; standard and enhanced);
The older a disclosure is the less reliable the information is, because the information it contains may not be up to date;
Information revealed through a CRB check reflects the information that was available at the time of its issue—a person may have committed a crime in the intervening period;
An organisation or employer may be required by law to carry out a fresh check against the Protection of Children Act list (PoCA) and/or the Protection of Vulnerable Adults Act list (POVA), thereby limiting the use of portability.
