If a school district provides a general education summer school, all students are eligible to enroll. That said, not all general education summer programs are appropriate for all students with special needs.
If a school district has access to an extended school year for special needs kids, the fact that any sped administrator would request that staff consult with he/she prior to writing extended school programming in an IEP is not in and of itself a violation. Fact is, staff should consult with administrative staff for a myriad of reasons. Kids with school related disabilities are usually encouraged to take part in an extended school year program IF data shows that the student has demonstrated or is likely to demonstrate a regression in skills without the ESY.
And yes, ESY is exorbitant. The transportation costs alone are very costly. A SPED administrator is supposed to review the IEP's of students for all manner of services. They are by extension, the representative of the district agreement for that IEP.
BUT-the fact that the administrator coupled her remarks to staff in an email and included the $$ issue, her communication is just dumb. She will have lost all integrity and now the district's IEP's will likely go thru a monitoring process which is also costly and time consuming.
