As a part of the Third Assessment of Science for the National Assessment of Educational Progress (National Assessment, Note 1.), an extensive battery of items dealing with the affective domain were included for the first time. Information for the National Assessment of Educational Progress is gathered from a stratified sample drawn from the entire United States. All questions are reviewed by education specialists (including science educators, measurement experts, and lay persons). The questions are administered to 2,500 persons selected to represent varying age levels. For NAEP studies, four samples are used, namely 9, 13 and 17-year-olds and a young-adult sample.
