No less than four different sets of regulations cover the use of a service animal by a person at school. Indiana law has the broadest definition of service animal. It  defines ”service animal” to mean any animal that helps with hearing, seeing, performing tasks, anticipating seizures, or addressing psychiatric or autism disabilities.  Indiana law prohibits an extra admission charge to an activity such as a ball game for a service animal (Ind. Code 16-32-3-1).  The Justice Department enforces the public facilities portion of the ADA and recognizes only dogs as service animals, but just recently added a special rule permitting miniature horses as a service animal. The role of a service animal for vision impaired students is recognized in IDEA and Article 7, and the EEOC uses a broader definition of service animal for workplace purposes. The City of Indianapolis was recently sued for refusing to allow an employee’s “papricka dog” to accompany her in the municipal workplace.  Experience teaches that most person who are accompanied to an activity by a service animal know their rights.
