In the TACS, IRATA breaks rope access climbing techniques down into two different and fairly broad categories: aid climbing (where you’re suspended with work positioning lanyards) and climbing with fall arrest equipment (where energy-absorbing lanyards or pre-installed fall arrest systems are used). In some instances, you might use a combination of both these techniques, especially within the training centre, where clearance distances are minimal.
Vertical aid climbing falls in the first of these two categories, and is only necessary for level 2s and 3s to prove competency on assessment day.
There are some situations where, to reach your work position, you may need to do some climbing. Vertical aid climbing is a more advanced technique, and could be used to climb a steel lattice tower, a series of bolt anchors in a wall, etc.
During your IRATA Assessment, L2 and L3 certifying techs will be asked to demonstrate competence performing a vertical aid climb, covering a vertical distance of at least 3 m.
L3 techs will also be asked to demonstrate competence assessing the suitability of this method for a variety of scenarios and structures.
In the TACS, IRATA specifies that you should be “progressing primarily in an upward direction.” In real-world situations where there are hazards or obstacles to avoid – or even if there is a vertical route that is less fatiguing – you might need to take a small diagonal or even horizontal detour to reach your work position. This isn't really applicable to the controlled space of our training facility where you'll be tested, so just focus on good climbing technique and covering those 3m of distance.
Your assessor will specifically be watching to ensure that you…
- Minimize potential fall factors, distances, and impact loads.
- Choose a short work positioning lanyard that simplifies any potential rescue and maneuverability.
There isn’t just one way to safely execute this, and a variety of lanyards and techniques can be used. We’ll go over a handful of these methods, and how to choose the technique/gear most appropriate for both the scenario and your ability, during your training week.

This is part of an ongoing series, where we’re breaking down IRATA’s syllabus and clarifying exactly what ‘demonstrating competence’ and ‘demonstrating awareness’ means, and what will be expected of you on assessment day. As an IRATA L2 certifying tech, you’re expected to be fully competent with the L1 Syllabus. To return back to the IRATA L2 Study Guide or IRATA L3 Study Guide, click below:
