Digital Technologies, programming NCEA 2016

One of the areas that I am interested in each year, is what is the condition of programming in New Zealand Schools.

While it has been going up year upon year, with 5884 students taking NCEA Level One programming in 2016. Up from 3246 when the standards was introduced in 2011. What does this look like nationally.

There are 430 schools that teach Technology at NCEA levels in New Zealand in 2016. I have used that as the base information.
The above map shows the areas of the country where Level One, Level Two and Level Three are taught.
