This revised data file includes corrections that were provided to NCES as a result of a special collection effort designed to address data quality issues found in the 1a release of this file. In May 2012, NCES became aware of data errors for key data items for several schools on the published version of the SY 2009-10 school file; in some cases these errors also affected district level data on the published 1a version of the LEA universe files for SY 2010-11. As a result, NCES conducted an in depth quality review of both the school and LEA universes for both the published SY 2009-10 school and LEA universe files and not yet published SY 2010-11 school and LEA universe files. During this review, NCES developed a revised editing strategy that more accurately identified data items that were likely to have errors. The review focused on school and school district enrollment, grade 12 enrollment, and free and reduced price lunch variables and related ratios such as pupil/teacher ratio, percent of enrollment from grade 12, and percent of students eligible for free and reduced price lunch. In the past data items were only compared to the reported data from the prior year for each school or LEA. The revised methodology used data from multiple years and was applied to both the reported data items and related ratios. Specifically, an average variation over the prior 4 years was computed based on the differences between each year and the other 3 years. Then, the average variation between the target year and the four preceding years was computed based on the differences between target year and each of the 4 prior years. The average variation for the target year was compared to the average variation among the prior years; cases with large differences were flagged as potential errors. Additionally, a requirement was added that in order for an item to be identified as a potential error, both the count and a related ratio must be identified as potential errors. For example, for total student membership to be flagged as a potential error, both total membership and a related ratio, such as pupil/teacher ratio, must be flagged.
