§ A teacher who taught a ministry-approved locally developed secondary school course related to Green Industries for two or more years prior to September 1, 2010, may be assigned to teach the technological education subject Green Industries. (See Reg. 298, subsection 19.1(3).)
For example
A teacher who taught a ministry-approved locally developed Landscape Architecture course in 2003 and 2007 may be assigned to teach Green Industries in technological education.
