What are the recommended leader ratios?
For school and youth groups there must be one adult leader of each sex if it is a mixed party, in a ratio of at least 1:15 (YHA recommends 1:10). For school groups YHA accepts teaching assistants, parents or guardians as sub-leaders, where there is a qualified leader assigned to each sex. We advise that you also check the leader ratios suggested by your Outdoor Education Advisor.
