"The Oklahoma State Department of Education (OSDE), Accountability and Assessment, conducts an annual data quality review to ensure the state and districts are receiving the highest quality data, and to better advise and partner with districts regarding their implementation of standardized procedures and security measures established for the Oklahoma School Testing Program (OSTP). This process fulfills requirements of the United States Department of Education (USDE) federal compliance guidelines. Data quality review at the state level includes, but is not limited to: reviewing the number of violations and irregularities reported, performing an erasure analysis, and verifying participation numbers for all students who are enrolled in the assessed grades or course tested. Information contained in this report summarizes the erasure analysis results for Spring 2011-12 testing for the federally mandated subjects of math, reading and English/Language Arts, and science."--Page 1.
