NAEP Technical DocumentationTreatment of Items in the Scaling of the 2000 National Science Scales (Accommodations Permitted)

The following items are provided.

Items Deleted From the Final Scaling
Cluster Items Created for Final Scaling
Recoding of Polytomous Item Categories for Scaling
Items Scaled Separately by Assessment Years
