Rural high school principals are defending the inclusion of courses in subjects such as tractor driving, farmbike riding and chainsaw use in the curriculum.
Timaru Boys' High School has 15 pupils in its chainsaw classes, and Temuka High School offers tractor driving.
Timaru Boys' deputy rector Nick Simpson said that offering such classes as a National Certificate in Educational Achievement (NCEA) subject met the demands of a modern economy.
He was reacting to Auckland Grammar headmaster John Morris' criticism of a range of NCEA subjects that included the operation of a chainsaw, as "ludicrous".
"We're short-changing our kids by offering that sort of thing," Mr Morris said.
