Gaps and Changes in Gaps between Selected Groups - Idaho
Reading, Grades 4 and 8, 2003 to 2005

 

The tabular performance gap displays below were acquired from the NCES website via the NAEP Data Explorer.  Table 1 shows gaps in average reading scale scores for four paired-groups of Idaho fourth graders, namely, (1) male and female, (2) White and Hispanic, (3) not eligible and eligible for free or reduced price lunch, and (4) 75th and 25th percentiles.  Table 2 displays corresponding reading gap information for the same four paired-groups of Idaho eighth graders.

4) Gap between Male and Female
  Male Female
  Average Scale Score Average Scale Score Difference
2005 218.3 (1.2) 225.3 (1.1) -7.0 (1.6)

From 2003 to 2005, the change in the gap was 1(2.4), which does not represent a significant difference between the two years.
4) Gap between White and Hispanic (Race/ethnicity used in NAEP reports after 2001)
  White Hispanic
  Average Scale Score Average Scale Score Difference
2005 226.1 (0.8) 199.3 (2.8) 26.8 (2.9)
2003 221.6 (0.9) 198.6 (2.1) 23.0 (2.3)
From 2003 to 2005, the change in the gap was 4(3.7), which does not represent a significant difference between the two years.
4) Gap between Not eligible and Eligible for Free/Reduced-Price Lunch
  Not eligible Eligible
  Average Scale Score Average Scale Score Difference
2005 230.0 (1.0) 210.3 (1.2) 19.7 (1.6)
2003 226.1 (1.4) 207.4 (1.4) 18.7 (1.9)
From 2003 to 2005, the change in the gap was 1(2.5), which does not represent a significant difference between the two years.
4) Gap between 75th and 25th Percentile
  75th 25th Percentile
  Scale Score Scale Score Difference
2005 245.0 (1.4) 201.6 (0.8) 43.4 (1.6)
2003 242.9 (1.4) 196.5 (1.9) 46.4 (2.4)
From 2003 to 2005, the change in the gap was 3(2.9), which does not represent a significant difference between the two years.

--- Sample size is insufficient to permit a reliable estimate.
Note: Score differences are calculated based on differences between unrounded average scale scores. In this table, significance tests were carried out for all changes in gaps. All other observed differences are not necessarily statistically significant.
