The Illinois Association for Pupil Transportation has been in existence since 1973. The membership consists of approximately 200 full and associate members. All members are involved either directly or indirectly in the safe transportation of Illinois school students. The IAPT hosts a conference annually that includes a large trade show.
The IAPT also holds a School Bus Roadeo and a Technicians competition. The winners of these competitions are then sponsored by IAPT to attend the National Competitions for these events.
