You can request a meeting to review and revise your child's IEP. But before you request that meeting, you need answers to several questions.
Why is your child failing regular education classes?
When the team decided to place her in regular education classes, what accommodations did they write in her IEP?
Did all her teachers implement these accommodations consistently?
Children with disabilities are entitled to supplementary aids and services so they can be educated in regular education classes with nondisabled children.
What supplementary aids and services did the team agree to provide?
Did the school provide these aids and services on a consistent basis?
Supplementary aids and services must be based on peer-reviews research "to the extent practicable."
Are the supplementary aids and services in your child's IEP based on peer-reviewed research?
The IEP team thought your child could handle the demands of regular education. If she is failing because she did not receive the accommodations and/or supplementary aids and services she needed, moving her back into a special education class is not the solution.
