A community police unit is to be set up as part of new moves to try and end the stand-off at the Holy Cross Catholic primary school in north Belfast.
The RUC said some of the children caught up in the dispute are among 70 applicants seeking compensation for post-traumatic stress.
Assistant Chief Constable Alan McQuillan said the incidents were blighting the lives of all those involved. The eight-week stand off between the two communities has cost the RUC an estimated £2 million.
Several meetings have been held in an attempt to find a resolution, but with no sign of a breakthrough, police say they hope both sides will use the Halloween holiday to negotiate a settlement.
In the meantime, they will be reassessing their operational plans.
A new unit of up to 25 officers is to be established to police the Glenbryn/Ardoyne area to provide round the clock, seven-day-a-week cover. It is likely to be up and running when classes resume in a week's time.
One women was arrested this morning when Protestants attempted to block children in fancy dress and their parents as they walked through their area to a mid-term Hallowe'en party at the school. Fr Aidan Troy, chairman of the school's board of governors, said the arrest was regrettable.
"With the children, and some of their parents in fancy dress, there was a wonderful carnival atmosphere. It has been weeks since there has been such joy and happiness among the children," he said. "I think it is totally regrettable somebody had to be arrested"
