Colts teams from under 9 to under 11 play 7-aside matches. Games are played on a reduced field size, this is a national policy designed to allow children to develop basic skills and knowledge of hockey, and the games are played without goalies. The seniors play full field hockey and in all the versions played, Hartmann House places a huge emphasis on safety. The school easily fields 4 senior teams and 5 colts’ teams; the boys get massive exposure playing in the country’s top festivals and tournaments. The first team participates in the Lusaka International School Invitational Tournament where they play eleven man and 7-aside matches.
