NNAS Silver Navigation Course

The National Navigation Award Scheme (NNAS) is a personal performance, non-competitive, incentive scheme for all ages. Training and Assessment courses use Harvey Maps of 1:25,000 or 1:40,000 scale, Ordnance Survey maps of 1:25,000 o 1:50,000 scale or orienteering maps of 1:10,000 or 1:15,000 scale.


Navigation in the countryside using skills acquired at bronze level and adding skills required to navigate to features and places some distance from paths and tracks, accurate compass work is required and an ability to use appropriate navigational techniques to go across country in some cases, e.g. choosing an appropriate attack point. Distance 5-8 kilometres.


Level 2 - NNAS Silver Award
Assessment Procedures

Assessment will be made on a continuous course (or courses) in open countryside or forest which turns frequently, includes uphill and downhill sections, and tests the ability to use attack points at the end of line feature routes in order to reach subtle location points. As for Level 1, any type of accurate map can be used and locations can be indicated by circles or grid references. The length of course will depend on age and fitness of participants as well as map scale, but will normally be between 5 and 8 km depending on roughness of the terrain.


Participants will be monitored for the frequency with which they check the accuracy of their chosen routes with reference to checkpoints (e.g. path junctions, field boundaries), their close attention to the map, and their decisiveness at times when they are unsure or lost. Practical assessment will be supplemented by oral and/or written examination as for Levels 1 and 3. The Navigator Silver Badge and Certificate will be awarded to successful candidates.

Silver Syllabus

  • Utilise the skills and techniques of the Bronze Award in the context of Silver Award navigation strategies.
  • Relate small hills, small valleys, prominent re-entrants and prominent spurs to their corresponding map contours. Use prominent hills, ridges, spurs and valleys as a means of navigation in good visibility.
  • Use landforms and point features to orientate the map and as collecting and catching features.
  • Use a compass to: Accurately follow a bearing; aim off; check the direction of handrails and other linear features.
  • Deviate briefly from a compass bearing to avoid obstacles or difficult terrain and accurately regain the original line.
  • Use back bearings to check route following accuracy.
  • Measure distance on the ground in varied, open terrain using timing and pacing and make practical allowances for any discrepancies.
  • Simplify legs using coarse navigation, attack points and fine navigation.
  • Recognise dangerous or difficult terrain on map and ground.
  • Plan and implement navigational strategies based on the above skills.
  • Maintain route finding accuracy in poor visibility or darkness.
  • Recognise a navigation error within a few minutes and apply appropriate relocation techniques.
  • Understand how personal fitness and nature of terrain affect route choice both at the planning stage and on the ground.
  • Understand the potential consequences of fatigue and physical discomfort in demanding terrain and/or extreme weather conditions.
  • Select appropriate clothing, equipment and first aid items for walking in open country in all weather conditions.
  • Demonstrate an understanding of the Countryside Code, current access legislation and the environmental impact of walkers on the countryside.
  • Understand the responsibilities of walkers towards other countryside interests such as farming, forestry and conservation.


Cost per person is £110 & VAT.
