Frequently asked questions
Are these questions from the actual exams? +
These are practice questions based on the topics and concepts covered in each certification exam. They are not taken directly from any official exam. Use them to identify weak areas and guide your study, then consult official study materials from EPA, OSHA, NATE, or your state licensing board.
What is the passing score for these certifications? +
Most of these exams require 70% to pass. The EPA 608 requires 70% on each section (Type I, II, III, or Universal). OSHA courses require 70% on the final assessment. NATE Core requires 70%. State journeyman exams for electricians and plumbers vary by state but typically require 70% to 75%. Check your specific state board for exact requirements.
How should I use these practice tests? +
Take the test once to identify your weak areas. Review the explanations for every question you miss. Study those topics using official materials, then retake the test. Repeat until you score above 85% consistently. The topic breakdown on your scorecard shows exactly where to focus.
