The sampling process for NAEP 2008 began with the selection of primary sampling units across the nation. Then schools from two sampling units in Idaho were picked for the 2008 assessments. Finally, students were selected from the sampled schools on a random basis for testing.
In the first stage of sampling, twelve Idaho (12) schools were selected from southwest Idaho --the "blue area" on the map to the right -- to take part in the NAEP 2008 National Arts Assessment or in Item Field Testing for NAEP 2009. Only one Idaho school was selected for the national arts assessment.
Then sixteen (16) Idaho schools were selected from southern Idaho -- the "yellow area" on the map -- to take part in the NAEP 2008 Long-Term Trend Assessment.
In the final stage of sampling, individual students were selected on a random basis to take part in the assessment. The number of students selected in a given school varied depending of (a) the size of the school, (b) the grade level or age of the students, and (c) the NAEP assessment for which the school was sampled.
Westat Inc, a NAEP contractor with headquarters in Rockville, Maryland, conducted the sampling process from start to finish. No Idaho educator participated in selecting the Idaho schools or the individual students in those schools.
