The series of change or growth maps below from NAEP 2007 Writing display how each Idaho demographic group in 2007 (i.e., all, male, female, White and Hispanic) compared to its Idaho counterpart in 2002. Each state is compared only with its own earlier performance. Comparisons of average scale scores are based on statistical tests (.05 level) that consider magnitude of differences and standard error. Idaho (and other states) coded in green had a higher average scale score in 2007 than it had in 2002 (i.e., a gain). A state in yellow had a 2007 average scale score that was not significantly different from its 2002 score.  A state coded in red had a lower average scale score in 2007 than in 2002 (i.e., a drop).
