NWSA practical exams are conducted in a real-world environment using an actual tower and associated materials. The TTT-1 exam is intended to replicate actual work activities done by technicians. The TTT-1 practical exam comprises six main tasks and must be administered by an NWSA-accredited Practical Examiner. Candidate's skills are tested in demonstrating ability to follow assembly instructions, proper tool use, donning of harness, climbing techniques, signaling, performing work at height (installation of an antenna on a tower and routing a jumper connection), weather proofing, and tying knots. Candidates are allowed two hours to complete the exam.
