MORE site supervisors are failing basic health and safety tests for the Construction Skills Certification Scheme than the workers they are in charge of.
And site managers are not performing much better, with one in 10 bosses failing the tests.
Figures unearthed by Construction News show that 22,602 site managers and 10,763 supervisors took the multiple choice tests last year in a bid to get their CSCS cards. Of those, 1,866 managers and 1,834 supervisors failed.
That compares with 32,700 operatives who sat the test, 5,082 of whom failed.
A source at the Construction Industry Training Board, which runs the scheme, said: 'We are happy with these pass rates but you would expect a higher percentage of managers and supervisors to pass.'
The figures were also blasted by Chartered Institute of Building president Stuart Henderson.
He described as 'shocking' the amount of 'practising managers who failed what must only be regarded as a threshold level health and safety test'.
Mr Henderson said: 'Think of the damage they can do. Not just to individuals on site, but to our industry's reputation.'
One union official said: 'It's pretty frightening that so many supervisors are failing.
'They are supposed to be in charge on site and enforcing safety standards.'
