About the Assessment: Types of Accommodations

Students assessed with accommodations typically received some combination of accommodations. In contrast to earlier assessment years in which students were only counted once in the category reflecting the primary accommodation provided, students were counted in the categories for each accommodation they received in 2009. For example, students assessed in small groups (as compared with standard NAEP sessions of about 30 students) were also usually given extended time and are included in counts for both groups.
