“Does your child have an IEP? Or is your child being evaluated for special education services? If so, it’s important to know that you and your child have legal rights and protections during this process. The Individuals with Disabilities Education Act (IDEA) offers these protections. They’re called procedural safeguards.
Procedural safeguards don’t spell out what services or should be in an IEP. Instead, they describe the ground rules for how you’ll work with the school.”
