Generate Sampling Weights Sample Clauses

Generate Sampling Weights. The contractor shall develop sampling weights necessary to produce estimates required for summaries and analyses as specified in the NAEP Design Plan prepared by the DAR contractor. • The student sampling weights shall be developed using procedures similar to those used in the prior NAEP assessments and described in the NAEP Technical Documentation. • The contractor shall provide both preliminary and final student and teacher sampling weights for operational assessments to the DAR contractor. • The contractor shall negotiate a schedule for the preparation of preliminary and final sampling weights with the DAR contractor. • The contractor shall maintain, for NCES inspection, the records and results of the statistical quality control checks used in creating all sampling weights and the data files which contain them. • The results of the sampling weights quality control checks for each operational assessment will be presented to NCES following the delivery of the final sampling weights to the DAR contractor. • The contractor shall provide student and teacher sampling weights to the DAR contractor on a schedule that allows the initial reports of mathematics and reading results in grades 4 and 8 to be released within 6 months of the end of data collection (unless otherwise directed by NCES). • Sampling weights for grade 12 students and teachers and all students and teachers in national assessments of other subject areas shall be transmitted on a schedule that allows the initial reports of results to be released within 12 months of the end of data collection. • According to NCES Statistical Standards, the contractor shall conduct a non-response bias analysis at any stage of a data collection with a unit response rate less than 85%. If the unweighted student response rate falls below 85%, the contractor shall conduct non-response bias analyses to determine whether or not the data are missing at random. Additionally, if the item response rate is below 85% for any NAEP questionnaire item, a nonresponse bias analysis is also required for each of those items (note: this nonresponse bias analysis does not apply to individual cognitive test items). The contractor shall develop a non-response bias analysis report for NCES approval following the format used for the 2013 and 2015 assessments. • The SDC contractor shall provide the DAR contractor with the data necessary to simplify the variance estimation process for primary and secondary NAEP student-centric and teacher- ...
