Most Canadians are absolutely crazy about their national sport. They begin playing at a very young age. Hockey rinks can be found in just about every hamlet. The Canadian climate tends to foster the sport with long, rather cold winters. Most private schools in Canada offer hockey at the intramural and varsity level. The coaching tends to be of a pretty high standard.
But what about south of the border? The expansion of the National Hockey League into southern and western states has created a whole new following. Thousands of young men suddenly want to be professional hockey players. They love the fast pace and excitement of Canada's national sport. So, if your son or daughter (yes, many coed and girls schools mount girls' hockey teams) is clamoring to go to a 'hockey' school, then, you can't do much better than some of the schools on the list below. These fine American private schools enjoy a great reputation for excellent hockey teams as well as superb academics. Who knows! Maybe he will end up on an NHL team.
