Operation Focus is meant to stop students from going over the top and will be employed tonight and next Thursday, when GCSE results come out.
Insp Sara Garwood is leading the operation and urged teenagers to celebrate without causing a nuisance.
She said: ‘Traditionally at this time of year, hundreds of young people in Jersey celebrate their GCSE or A-level results.
While the majority do this without causing a problem, in the past we have found that some large groups are badly behaved, and this can cause problems for other people who can feel intimidated by bad behaviour.
‘Last year the centre of activity was Winston Churchill Park in St Brelade’s Bay, and several complaints were received from members of the public, as well as from residents and businesses in the area.
‘However, officers will be ready to attend any location where problems are occurring.
Where possible, officers will be patrolling with members of the honorary police.’
