OREGON, Wis. -- An Oregon mother said her son wasn't allowed on a school field trip because of his disability.

The Oregon School District will meet with the family Wednesday night as part of a mediation session.

The parents said they suggested to teachers that they would chaperone their son, or even limit his time spent at the field trip. They said they even went to the school board meeting Monday night for one last chance.

But the overnight trip has come and gone, and now the family said it wants to make sure conflicts like this don't happen again.

Mother Cathy Hasslinger said her son, Quinn, fights a daily battle to manage his autism.

"Quinn is a great kid. He's got a lot of interests. He's 13 years old, and he's got Asperger's, which is high-functioning autism, and that definitely affects his approach to life," Cathy Hasslinger said.

His classmates had a field trip set for this week, one that Cathy Hasslinger said her son wasn't allowed to attend because of his disability.

"We really wanted Quinn to go on this trip. This is a two-day camping trip, team building exercises, a chance to get out there with his buddies," Cathy Hasslinger said.

For the trip, the students at Oregon Middle School left school grounds, spent time overnight and participated in outdoor activities.

The school district said that when it comes to questions over participation, each case is handled separately.

"We do not have a district policy that governs whether a student goes or doesn't go on a particular field trip. That's not something that exists," said Brian Busler, Oregon School District superintendent.

The Oregon School District would not comment on the specifics of the Hasslingers' concerns, but it said it hopes to continue dialogue about the situation.

"One of the things that we're always willing to do is take a look at the rearview mirror and if there's something that we could've done better, we'll make that change in the future," Busler said.

"I kept expecting that phone to ring, for there to be a phone call saying, 'We've reversed our decision, pack your bags, your son is going.' But unfortunately that call didn't come," Cathy Hasslinger said.

The Hasslingers said Wednesday's mediation session will be all about clarifying issues that have been struggles for many families on the autism spectrum.
