Why Attend
This is Indiana’s first full-week collaborative exam review, offering intensive in-person training using IDEM study guides and manuals. It is designed for maximum knowledge retention and higher pass rates, provides access to the latest training materials, and is ideally timed to allow participants to review just before taking the exam.

Important Notes
The course is limited to 50 participants, so early registration is encouraged. Prerequisites include attending the mandatory September orientation, completing 18 hours of homework and online preparation sessions via Teams, and participating in 32 hours of in-person instruction from November 3–6. The exam application deadline is September 23, 2025, and applications must be postmarked to IDEM. Participants should bring printed study guides, formula sheets, and manuals appropriate for their exam grade. IDEM exams are not graded on-site; those wishing to receive same-day results should consider testing through Ivy Tech, coordinated independently. Registration closes August 31, 2025, and the online orientation sessions will take place September 3 and September 22, 2025, from 9:00–11:00 AM.
