NAEP Technical DocumentationYear-Round Schools

In NAEP assessments, the year-round factor is an adjustment to reflect that some students in year-round schools are not in school during the assessment period (OFF). As this set is a randomly selected set, the frame of students from which the assessment sample was drawn (without the OFF group) is viewed as a random sample from the full set of students (frame plus OFF). The YRRND_s factor was 1/(1-OFF) for the school. The weights including this factor allowed the assessed sample to represent the full student body within these schools.
