Employees fear being swamped with data from schools

They also argue that computer systems at the SQA are still inadequate and that employees believe they will soon be swamped by data from schools which will be no easier to handle this year.

MSPs on the education committee will also be told that there are suggestions of intimidation, with staff being bullied into working overtime for no extra pay.

Union representatives warn that stress levels within the organisation are reaching worrying heights and that the workforce is apprehensive about the immediate future.

But they do concede that some of their concerns are already being addressed.

Last year, results were posted out on 9 August, but the results were strewn with errors.

Warning system

Following a parliamentary inquiry into the marking process, the Scottish Executive vowed to ensure the chaos would never be repeated.

A wholesale clear-out at the exams authority was announced by Education Minister Jack McConnell in November.

A new board was put in place and an action plan unveiled to prevent further exam problems.

The measures announced include an early warning system, which will allow pupils, parents and teachers to voice concerns about the administration of exams.

A senior civil servant has been appointed as a troubleshooter to act as a link between the Scottish Executive and the SQA.
