What the Course Entails and Exam Details

This intensive course covers a wide array of technical subjects required for accurate fire behavior predictions. The syllabus includes critical modules on topography and its effect on fire spread, in-depth weather analysis (stability, wind types, local influences), utilizing USFBPS fuel models, understanding fuel moisture content, and the actual mechanics of fire behavior models. Students must gain proficiency in both manual calculation methods using fire behavior nomograms and electronic processors like BehavePlus software, as well as learn how to document, interpret, and effectively communicate their outputs and predictions for fireline safety, briefings, and planning. Satisfactory completion of the S-290 prerequisite and a pre-course assessment/work is mandatory, demonstrating a solid understanding of the basics before diving into complex calculations.

What to Expect in the Final Exam

The actual S-390 final examination is generally a significant portion (around 90 points out of a total 100 in some structures, including a group exercise) of your overall course grade. It is typically a hybrid assessment, blending rigorous multiple-choice questions with practical problem-solving components. You will likely be presented with detailed scenarios involving maps (like topographic and specific training maps), weather data, fuel descriptions, and then asked to perform manual or electronic calculations using the tools you’ve learned. This can include predicting rate of spread, flame height, fireline intensity, and identifying potential extreme behavior. The passing score is usually set around 70% or higher. Expect a timed component, perhaps spanning two hours or more for the complete exam, designed to simulate the time-sensitive decision-making required on the fireline. You will be expected to effectively utilize and interpret outputs from nomograms, the Fire Behavior Handbook (PMS 410-2), and potentially BehavePlus software where applicable.

How to Study and Exam Centers

Preparation for both the course and the final exam requires dedication and practical application. Actively engage in all coursework and exercises. Thoroughly complete all required pre-course work. Dedicate time to mastering the manual calculation methods using fire behavior nomograms; speed and accuracy in interpreting these charts are key. Get familiar with BehavePlus v6.0 or current versions well before the course. Utilize practice problems in the Student Workbook and seek out reputable practice exams to simulate the testing environment. Form study groups to discuss complex scenarios and calculation methods. Review key NWCG publications like the Fireline Handbook Appendix B and fuel model guides. Remember, the core NWCG S-390 course and its final certification exam are provided through various authorized agencies, wildfire academies, community colleges, and specific physical testing environments, often listed through the Wildland Fire Learning Portal or official training websites. They are generally not administered at generic commercial testing centers but in structured, specialized settings by accredited wildland fire training providers. Ensure you are taking the official NWCG-certified course and its integrated exam. Practice tests can be used for self-study and preparation for the rigorous course content.
