The government's advice has not changed since 2018. The following advice can be found at https://www.gov.uk/government/publications/health-and-safety-on-educational-visits/health-and-safety-on-educational-visits#evaluating-trips and was published on 26/11/2018.
1. The 2 main types of trips
1.1 Routine visits
These involve no more than an everyday level of risk, such as slips and trips and are covered by a school’s current policies and procedures. They only need a little extra planning beyond the educational aspect of the trip. They can be considered as lessons in a different classroom.
1.2 Trips that need a risk assessment and extra planning
These are trips not covered by current policies. This could be due to things like:
the distance from school
the type of activity
needing staff with specialist skills
Sometimes a school may just need to review its current plans or arrangements that were successful on previous trips. However, some trips will need risk assessments, detailed planning and informed approval of headteachers or governing boards. The person given the job of managing this should:
have the skills, status and competence needed for the job
understand the risks involved
be familiar with the activity
Plans should be proportionate and sensible, focusing on how to manage genuine risks.
2. When to get consent from parents
A school must always get written consent for nursery age children.
