The "29th Annual Report to Congress on the Implementation of the Individuals with Disabilities Education Act, 2007" follows the 2006--i.e., the 28th annual report--in sequence. The "29th Annual Report to Congress" is, however, the first to have three volumes. In the 28th and previous editions, volume 2 consisted of data tables and data notes for Parts B and C. With the 2007 or 29th annual report, volume 2 now contains only Part B data tables and data notes and volume 3 contains data tables and data notes for Part C. Volume 1 presents a picture of how children and students are being served under the law nationwide and provides profiles of individual states' special education environments and early intervention settings. It also includes tables of states rank-ordered by their reported data on exiting, dropouts, educational environments and early intervention services and settings. Lastly, it contains abstracts of research projects funded by the National Center for Special Education Research and other studies and evaluations for assessing the implementation and effectiveness of key programs and activities supported under the "Individuals with Disabilities Education Act" ("IDEA"). Volumes 2 and 3 of the "29th Annual Report to Congress" consist of tables that also were compiled from data provided by the states. Such data are required under the law. In fact, the collection and analysis of these data are the primary means by which the Office of Special Education Programs monitors activities under "IDEA", thereby helping to ensure the free appropriate public education of all children with disabilities. Data tables in volume 2 cover a multitude of topics regarding states' implementation of "IDEA", Part B; data tables in volume 3 cover a multitude of topics regarding states' implementation of "IDEA", Part C. In the analysis of data presented in volume 1, there are frequent references to specific tables in volumes 2 and 3 as sources. In that sense, volumes 2 and 3 can be used as appendices to volume 1. However, the tables in volumes 2 and 3 provide much more extensive data than are referenced in volume 1. As such, they may be used by anyone interested in doing further analysis of state activities funded under "IDEA". Appendices include: (1) Data Notes for "IDEA", Part C; (2) Population Data; and (3) Budget Data. (Contains 40 tables and 2 footnotes.)
