This is a classic instance of retaliation under Section 504 of the Rehabilitation Act of 1973 and the ADA. I hope the parent pursues an OCR complaint and other remedies. She and others needing help with lawless school districts might want to join the Council of Parents, Advocates, and Attorneys (COPAA) at www.copaa.org and participate in the listserve, for lots of helpful free advice and support.
The South Carolina parents have filed Office of Civil Rights complaints and the investigation is ongoing.
Grumpy Educators reported that the student has now enrolled in a public middle school and his complex medical condition and recommendations of the medical team apparently will be honored.
UPDATE: A comment added to the Ed Week follow up article is worth reading.
"Thanks for the followup on this story. I am concerned that any virtual school does not recognize medical advice as official. I thought virtual schools were often chosen by families because of medical conditions a child might have that would make attending a regular school difficult. This situation seems to have flown in the face of what was best for this student. After reading your original article, I contacted this school via facebook and was advised that to eliminate the possibility of a medically fragile student having to endure any state mandated tests, it would be best to enroll said child in the private virtual school also run by this company.
