NAEP science scores are reported on a separate 0–300 scale for each of the three grades assessed. Beginning in 1996 at the national level, and in 2000 at the state level, administration procedures were introduced that allowed the use of accommodations for students who needed them. In addition to allowing for accommodations, the 1996 and 2000 national results at grades 4 and 8 may differ slightly from those previously reported due to changes in the sample weighting procedures. Read more about the 2005 science assessment on the NAEP website. Read how the assessment was developed, what it measures, and how it was administered.
