Sampling Within Schools in the 2001 National Main Assessment


Assignment of Sample Types of Schools

Assignment of Sessions to Schools

The second stage of the national main sample design was the selection of the school sample. Schools were selected with probability proportional to size at rates targeted to meet required student sample sizes.

The students selected for inclusion in the sample (in either the initial sample, Black and Hispanic oversample, or the SD/LEP oversample) were allocated to a session based on the final number of sessions assigned to the school and whether the school was public or private.
