NAEP Technical DocumentationStudent Sample Selection for the 2011 Private School National Assessment

The target student sample size within sampled schools for the fourth and eighth grades was 63 students. However, schools with 70 or fewer students automatically had all students sampled. In addition, at grade 4 only, a school that had more than 70 students but fewer than 121 could choose to have all students sampled.

There was only one spiral type for each grade. The percentage of booklets by subject within the spiral for each grade is given below.

The process of student list submission, sampling students from year-round schools, sampling new enrollees, and determining student eligibility and exclusion status was the same as for the state NAEP student sample.
