(a) Note that the 2008 NAPLAN tests replace previous individual state and territory-based tests within a new assessment framework. The new national scale is not directly comparable with previous state and territory-based tests and therefore with previous years' benchmark results.
(b) Students who were absent or withdrawn from testing are not classified as assessed students and are not included in the benchmark calculations. The proportion of absent and withdrawn students varies considerably across jurisdictions, hence caution should be exercised when comparing results.
(c) The achievement percentages reported in this table are subject to error and have 95% confidence intervals. The confidence interval for year 5 Tasmanian students reaching the reading benchmark is 1.4%, meaning there is a 95% chance that the true percentage lies between 88.3% and 91.1%.
(d) The achievement percentages reported in this table are subject to error and have 95% confidence intervals. The confidence interval for year 5 Australian students reaching the reading benchmark is 0.3%, meaning there is a 95% chance that the true percentage lies between 90.6% and 91.2%.
(e) The achievement percentages reported in this table are subject to error and have 95% confidence intervals. The confidence interval for year 5 Tasmanian students reaching the writing benchmark is 1.1%, meaning there is a 95% chance that the true percentage lies between 91.5% and 93.7%.
(f) The achievement percentages reported in this table are subject to error and have 95% confidence intervals. The confidence interval for year 5 Australian students reaching the writing benchmark is 0.2%, meaning there is a 95% chance that the true percentage lies between 92.3% and 92.7%.
(g) The achievement percentages reported in this table are subject to error and have 95% confidence intervals. The confidence interval for year 5 Tasmanian students reaching the numeracy benchmark is 1.2%, meaning there is a 95% chance that the true percentage lies between 90.9% and 93.3%.
(h) The achievement percentages reported in this table are subject to error and have 95% confidence intervals. The confidence interval for year 5 Australian students reaching the numeracy benchmark is 0.2%, meaning there is a 95% chance that the true percentage lies between 92.4% and 92.8%.
