Coaches in the soccer program at the Australian Institute of Sport (AIS) do not really have to consider this question. in their case, access to players is unlimited. Most of the squad are in residence at the institute and could train under the coach twice a day if necessary. But because the players constitute a development squad aged between fifteen and sixteen years, the aim of the program is to increase their game skills as much as possible during their 18-24 month AlS scholarship.
