This report provides selected results from the 2002 National Assessment of Educational Progress (NAEP) for Idaho's public-school students at grades 4 and 8. Since 1992, reading has been assessed in four different years at the state level (at grade 4 in 1992 and 1994, and at both grades 4 and 8 in 1998 and 2002). Idaho participated in the 1992, 1994, and 2002 assessment at grade 4. In 1994, however, Idaho did not meet the criteria for reporting public-school results. At grade 8, Idaho participated only in 2002. Key findings for grade 4 are: the average scale score for students in Idaho was 220, which did not differ significantly from that of 1992 (219); students' scale scores in Idaho were higher than those in 17 jurisdictions, lower than those in 11 jurisdictions, and the difference was not found to be significant for 19 jurisdictions; and the percentage of students in Idaho who performed at or above the "Proficient" level was 32%, which was greater than that in 1992 (28%). Key findings for grade 8 are: the average scale score for students in Idaho was 266; students' scale scores in Idaho were higher than those in 20 jurisdictions, lower than those in 7 jurisdictions, and the difference was not found to be significant for 19 jurisdictions; and the percentage of students in Idaho who performed at or above the "Proficient" level was 34%. After an introduction, the report presents overall results, comparisons between states, reading performance by demographic characteristics, and it discusses moving toward a more inclusive NAEP, and where to find more information.
