The new law comes into effect on 1 January

More than 90% of the authorities which took part in the latest survey said they were confident that they would be able to comply with the new law.

But only 30% said they had trained their staff, although a further 63% still intended to do so.

The Scottish Information Commissioner described the study as "encouraging".

Kevin Dunion said: "Most authorities have a positive attitude towards their obligations and are taking steps to improve their systems and to train their staff.

New rights

"But we are also aware that some sectors are less than enthusiastic about the new right to know or have underestimated the challenge.

"The ultimate test of whether enough has been done will come when people exercise their new rights in the new year."

From 1 January, public authorities will have to respond to every written request for information within 20 working days.

Kevin Dunion said he was encouraged by the survey

Earlier research published in March suggested that 83% had a positive view of the act.

That figure had risen to 88% in the new survey, which received 228 replies from public authorities.

The study said that 92% of those questioned were either fairly or very confident of their ability to comply with the legislation.

Primary care providers, such as GPs, dentists, opticians and pharmacists, were found to be the least prepared.
