The report, released by Bracknell Forest Borough Council's Youth Services last month, exposed Sandhurst as "the most disadvantaged rural parish in the borough".
Increased rates of teenage pregnancy, significant levels of youth unemployment and high numbers of youth crime were some of the figures revealed.
But last week police confessed the figures given for the number of arrests of children attending Sandhurst School may have been wrong.
The report quoted nearly 50 pupils at Sandhurst School being arrested between 1998 and 1999 - but police now believe the figure to be just over half this.
Bob Cunningham, youth and schools officer for Bracknell Forest Thames Valley Police, explained the error.
He said: "The collection of data relating to offenders has historically been a difficult process and the systems in place are not 100 per cent accurate.
"The figures quoted by Youth Services were those given to them by the police.
"New processes of data management suggest the number of arrests of children attending Sandhurst School for that period may not have been as
high as originally quoted to Youth Services."
He added: "Recent analysis of the data for the period September 1998 to August 1999 suggests the level of arrests of known Sandhurst School pupils was 29.
"The figure of Sandhurst School pupils arrested over the same period last year between September 2000 and August 2001 suggests there were seven arrests.
"This represents the only fall in arrests in any school on our area.
"We believe this reflects favourably upon the work carried out by Sandhurst School and all the agencies involved with young people in that area over the last few years."
Sandhurst School headteacher Andrew Fletcher, who slammed the figures and comments as "misleading" and "inaccurate" at the time, said on Tuesday he was disappointed with the way the report had been handled.
He added: "I always wondered about the accuracy of these figures and all the others and why they were taken from four years ago - they show no pattern which should be the important thing.
"Obviously we were disappointed to find the figures were so inaccurate but it is good to know the number of arrests are far fewer than originally reported.
"The disappointing thing was the lack of partnership and consultation with the school before this report was released.
"I would have liked an acknowledgement or apology."
