Design and Select School Samples Sample Clauses

Design and Select School Samples. The contractor shall develop sampling plans, based on the assessment design specifications provided by the NAEP Design, Analysis and Reporting (DAR) contractor, for each of 4th, 8th, and 12th grade and ages 9-, 13-, 17-year old Long-Term Trend operational assessments, pilot and field tests, HSTS, bridge studies and special studies as listed in the Overview section. • Basic design features for NAEP samples are as follows: o NAEP samples are geographically and regionally representative of the nation including private schools, the reporting jurisdictions, and other reporting subgroups; o NAEP schools and students are chosen with a measurable probability of selection; o NAEP samples control for school overlap between assessment cycles across years; o Appropriate school variables such as type of school, school-level student achievement, and type of location are used to develop a stratified random sample; o NAEP national, state and district samples are of sufficient size to generate standard errors for relevant populations and subpopulations (e.g., white, black, American Indian and Hispanic students, English Language Learners) similar to previous NAEP assessments; o All national NAEP samples shall include, as a component, Large Central Cities; o NAEP samples are optimized by combining state and Trial Urban District Assessment (TUDA) samples into a nationally representative sample where possible; and o NAEP sampling methodology for selecting the sample and computing the weights should support continuation of trend reporting. • Furthermore, NAEP samples shall, to the extent possible: o minimize effects due to clustered sampling; o minimize cost and burden; o ensure that sampled students are assessed in only one subject area unless otherwise directed; and o minimize (or maximize depending on the design requirements) sample overlap with other NCES surveys. • Due to a two to three year lag time between the release of CCD files and the current population of schools, the SDC contractor shall work with the NAEP state coordinators (through the NAEP Support and Service Center) to update the list of eligible schools. • The SDC contractor shall propose and implement a plan that will use historical frame information from previous NAEP assessment cycles to provide feedback to and update / augment the most recently available CCD data, with the goal of relieving as much of the burden as possible from the NAEP state coordinators when they update their lists of eligible schools. ...
