Ninety-one North Walsham High School students slept under the stars as part of the Duke of Edinburgh bronze award.
Students have been working towards the award by volunteering within the community and gaining skills in their own time.
School spokesman Suzie Sharp said: '91 students had three training days for their practice expedition.
'Over the first two days, students took part in several sessions to gain the skills needed. These sessions consisted of first aid, tents and rucksacks, food and cooking safety and maps and writing route cards. They also took part in team building exercises.
'All 91 students took part in a sleep-out on the school field. Students used their new skills to put up tents, cook their evening meal and practise for their expedition. The next day students used their map reading skills on an unsupervised walk to Bacton woods and back. They rose to the challenge remarkably well and learnt a lot.'
