NWSA practical exams are conducted in a real-world environment using an actual tower and associated materials. The TTT-2 exam is intended to replicate actual work activities done by technicians. The TTT-2 practical exam comprises five main tasks and must be administered by an NWSA-accredited Practical Examiner. Candidates' skills are tested in demonstrating a complete PPE inspection, setup of a capstan hoist,
hoisting operations using different rigging configurations (trolley/tag system and heel block system), and selecting and installing all components associated with a guy wire.
