• Time Limit: Candidates are typically given 2.5 hours to complete the standard certification exam.

• Number of Questions: The standard treatment and collection system exams consist of 100 questions.

• Passing Score: A scaled score of 70% or higher is required to pass. The use of scaled scoring ensures an equitable assessment across different versions of the test.

How to Study and Exam Centers

Preparation is paramount for success on this exam. Utilize these strategies to build your knowledge and confidence:

• Structured Study: The Fleming Training Center in Murfreesboro is a primary resource, offering a range of advanced classes, study guides, and the TNPOP Academy, specifically designed for Tennessee operators.

• Practice Exams: Engaging with comprehensive practice exams is essential. Look for resources that simulate the computer-based format and difficulty level of the official test to identify knowledge gaps.

• Manuals and Guides: Study the standardized "Need-to-Know Criteria" provided by the Association of Boards of Certification (ABC), which forms the basis for many operator exams. Review state-specific manuals from TDEC.

• Math Practice: Dedicate significant time to practicing wastewater mathematics, as these problems are often weighted heavily.
