The class was usually split up in to groups of about 10, depending on age / proficiency. There'd be a teacher leading each group. There would also be the lifeguards from the pool. If I remember rightly, this was at least two, if not more -- there always seemed to be one sitting up in the high chair, and there always seemed to be one patrolling the pool edge. It was a 25m pool, and while the school was there it was closed to the wider public.
