Applicants who qualify will be sent an eligibility letter. Letters to applicants who do not qualify for any of the ten exams must be signed by the branch chief. Such declarations of ineligibility may be appealed. However, most exams are graded within one week. Seventy percent is a passing score, and whether an applicant passes or fails is public information.
Individual scores are confidential.
IDEM maintains a question bank, or list of all possible questions, from which the 50 questions for 2 exams and 100 questions for the other 8 exams are drawn. All Operator Certification Cards are valid for only 2 years, and expire on June 30th of the second year after which they were first issued or renewed. There are approximately 4,300 IDEM Certified Wastewater Operators within Indiana, and so more than 2,000 certifications expire each year. Continuing education hours can be submitted at any time, so are usually submitted immediately following course completion. Each year, all operators whose cards are scheduled to expire in that year are notified by mail that they need to renew their Operator Certification Card.
