The problem with NAPLAN is that not only do the normal test papers distributed during regular test time consume trees, the test prep does as well.
My neighbour, who is a primary school teacher, said that at their school, every kid from years 2-7 are going to sit last year's NAPLAN test. Soon an email was sent out: people are using up too much paper!
She sent an email back with the following message:
"300 students x 2 booklets for each (she missed out the reading comprehension one) x approx 10 pages for each booklet. Hmm. Wonder where the paper's going.
