The CRB infuriate me!
The idea is fair enough - check that there are no criminal convictions or cautions relating to children, for people working with children.
However...
I despise the fact that I have to have one done for every supply agency I work for, at a cost of £36 each. This is payable to what is essentially a private company. But do they do the checks themselves? No. They send the paperwork off to the relevant police forces according to the previous addresses listed on the form.
If you have two going through the system at once this slows it down. According to the helpful man at the CRB this is because "the police forces will be suspicious of two for different employers."
Having collated all the information from the relevant forces, can the CRB hold this data? No. Due to the Data Protection Act, apparently.
So, having had one check done, if another is required a month later, the paperwork must be sent to the same police forces, representing where you have lived for the last five years. Common sense would state that this should only be done for the intervening month, or time since the last check. But that would be too simple.
The employer, having received a copy of the CRB form, is only allowed to retain it for a short while (3 or 6 months) before they have to destroy it. Data Protection Act again.
Oh, and the CRB can obviously only guarantee the content of the CRB from up to the day it is printed.
I'm not sure the CRB in its current form is really doing the job it was intended for.
Incidentally, on the TES website there are a number of horror stories concerning occasions on which the CRB have made mistakes.
