applications currently taking a month, this promises to be a long and arduous process. The current record for a CRB check is 1,767 calendar days. But the ISA estimates that a registration should take no more than seven.
The cost of a one-off registration will be pound;64, and schools and other institutions that look after children or vulnerable adults can check the register online for free.
But grey areas remain. The law dictates that anyone who works in schools frequently must be registered with the ISA. What constitutes "frequently" has yet to be clarified. However, it is understood this will be defined in the next few weeks. And it is possible that Mr Pullman's opposition will influence the decision.
ISA scheme criticised
Some critics disapprove of the scheme because it suggests that all potential child-workers are presumed guilty until proven innocent. Others feel that once the register has bedded in, it will encourage children to see all adults as potential paedophiles. There are also worries that the regulations represent an infringement of civil liberties, in the same way as ID cards.
There are also concerns about how such an enormous register - membership is expected to reach 11.5 million - will be managed.
Tom Foster, of the National Association of Head Teachers' policy, politics and education department, believes the formation of the ISA is a purely political decision that is fraught with danger.
"The chances of this going pear-shaped are legion," he said. "It won't stop the wrong people being registered and they will only be removed later."
The Association of Teachers and Lecturers is also concerned that the new system will mean "undue delay" to checks.
Kehinde Adeogun, the union's solicitor, said: "We understand and support the procedures, but we don't want a delay to our members taking up employment. The Government is fully aware of our views and the difficulties which might be encountered."
Teaching unions to converge
Unions are set to meet regularly in the autumn to discuss the problems, which may vary across the country as some police forces are more efficient than others at processing CRB forms.
Supporters of the new regulations say they represent an improvement as an individual's records can be automatically updated, whereas the CRB check is not amended over time.
Most fundamental is the argument that a constantly updated register will reduce the chances of another Ian Huntley being employed to work among children.
ISA chief executive Adrian McAllister told The TES: "Despite the furore, I think what gets overlooked are the views of the parents.
"They don't understand what all the fuss is about. They just want to be sure that they can trust the people that are looking after their children."
Certainly, to get the ISA up and running is a mammoth task. A number of the most important decisions are yet to be made, and its many implications are yet to be felt. Whatever the future, it is unlikely to happen quietly.
CRB, ISA and List 99 -related statistics
The ISA replaces the controversial List 99, and the Department for Children, Schools and Families will hand responsibility for vetting to the new organisation.
Of the 248,220 disclosure applications from teachers in 2008, police national computer checks revealed 6,750 criminal convictions.
The Criminal Records Bureau received 252,872 disclosure applications from teachers in 2007. Of these, 6,013 disclosure certificates revealed criminal convictions.
Teachers can appeal against ISA judgments by disputing facts or by defending themselves - for example, if a criminal conviction dates from a long time ago or has no relevance to the job for which they are applying.
