As a teacher, I would say that the My School/NAPLAN results aren't always the best way to judge a school. The data results can be skewed for many reasons. The school I work in for instance is a very small school with two special classes in it as well. As a result, at NAPLAN time it is not unusual to only have 15-20 mainstream students in a particular year level taking the test. If you then add to the mix 2-3 students with special needs (who's parents sometimes opt to have their student take part - which they have every right to do), our combined result can actually turn out to be below average due to the very low scores that some of these students with special needs receive. It therefore falsely makes our school seem 'not as good' IYKWIM?
