This data contains all instances of restraints and seclusions that public schools self-reported during the 2011-2012 school year. It is broken down by state, district, and school. This is the first time the federal government has attempted to collect this data from all schools, though beware: many school districts did not report. ProPublica used this data in our story on the use of restraints at school. Read our reporting recipe, below, for tips on how you can report this story.
