STEN Qualification Requirements

Required Training

Required Experience

  • Satisfactory performance as an Engine Boss, Single Resource (ENGB)
  • AND Completion and Certification of NWCG Strike Team Leader Engine (STEN) Position Task Book, PMS 311-10 (see note)

Note: The Task Force Leader (TFLD) and Strike Team Leader (STCR, STEQ, STEN) PTBs are combined. However, the positions are not combined. Strike Team Leader tasks are completed only once. The required experience for TFLD must be met before completing additional TFLD tasks.

Upon satisfactory performance in the prerequisite Single Resource Boss position, the specific Strike Team Leader PTB may be initiated. Once qualified as a Strike Team Leader, any additional Single Resource Boss qualifications will also qualify the individual in that corresponding Strike Team Leader position—without having to complete the Strike Team Leader PTB for the new position—once agency certification is documented on the PTB “verification/certification” page.

Duties involve fieldwork requiring complete control of all physical faculties and may include considerable walking over irregular ground, standing for long periods of time, lifting 25 to 50 pounds, climbing, bending, stooping, squatting, twisting, and reaching. Occasional demands may be required for moderately strenuous activities in emergencies over long periods. Individuals usually set their own work pace.
