NAEP Technical DocumentationTarget Eighth-Grade Private School Sample Sizes

This table presents the eighth-grade target private school sample sizes for the NAEP 2002 national main assessment. The first column shows the target student assessment yields for the operational assessments (national main reading and writing). The second column then adds the targets for the field trial and equating assessments. These overall targets are then adjusted upwards to allow for school and student nonresponse. The projections for these are the actual response rates in the NAEP 2000 assessment (for each grade and private school subgroup separately). The final targets in the last column of the table are used then to determine school sample sizes and sampling rates.

Target private school sample sizes, grade 8 national main assessment, by reporting group: 2002

Reporting group	Operational assessment target	Overall target including field trial and equating assessments	NAEP 2000 school response rate (percent)	NAEP 2000 student response rate (percent)	Nonresponse adjusted target
Total	12,000	17,300	†	†	22,200
Catholic	6,000	8,650	91.3	95.9	9,880
Lutheran	1,500	1,765	92.6	96.1	1,980
Conservative Christian	1,500	2,295	70.0	95.6	3,430
Other Private	3,000	4,590	70.0	94.9	6,910
NOTE: Detail may not sum to totals because of rounding. Only the reporting group NAEP 2000 school and student response rates were used in the calculation of targets (i.e., for Catholic, Lutheran, Conservative Christian, and Other Private separately), not the overall private school response rates. The latter were not retained in the calculation of targets (they are replaced with a † ). The overall private adjusted target is the summation of the four reporting group adjusted targets. The response rates in the table are rounded to three digits, so the adjusted targets given in the table may not match adjusted targets computed using the presented numbers in the table.
