No Child Left Behind (NCLB) legislation focuses attention on high expectations for all students in learning grade level academic content, and requires that disaggregated participation and performance data be reported for students with disabilities and English language learners (ELLs). Although not required by law, some states have reported data disaggregated for students with disabilities who are also ELLs. This study summarizes the extent to which states reported these data in 2006-2007, and how the online reporting of participation and performance for these students in 2006-2007 compared to previous years. Eleven appendices are included: (1) Sample Letter Sent to Assessment Directors; (2) Example of Verification Tables Sent to State Assessment Directors; (3) Status of Disaggregated Data (Participation and Performance) for ELLs with Disabilities on Regular State Tests in the Fifty States and Unique States Across 2005-06 and 2006-07; (4) Status of Disaggregated Data (Participation and Performance) for ELLs with Disabilities on Alternate State Assessments in the Fifty States and Unique States for 2005-06 and 2006-07; (5) Status of Disaggregated Data (Participation and Performance) for ELLs with Disabilities on State Assessments Administered to ELLs or in Another Language in the Fifty States and Unique States Across 2005-06 and 2006-07; (6) Disaggregated Participation Information for ELLs with Disabilities on Regular State Assessments for the Fifty States and Unique States for 2006-07; (7) Disaggregated Alternate Assessment Participation Information for ELLs with Disabilities on Regular State Assessments for the Fifty States and Unique States for 2006-07; (08) Disaggregated Regular Assessment Performance Information for ELLs with Disabilities for the Fifty States and Unique States for 2006-07; (09) Disaggregated Alternate Assessment Performance Information for ELLs with Disabilities for the Fifty States and Unique States for 2006-07; (10) Tables With Data for 2002-2003; and (11) Participation and Performance for Students Tested with Accommodations.
