Checkpoints

In orienteering, checkpoint markers are what participants locate using their maps. Students need a way to prove they visited each checkpoint. There are several options, from simple to high-tech.

Checkpoint Markers​

Any visible, consistent marker works. Options include:

  • Cones with letter codes written on them (simplest for schools)
  • Orienteering flags (orange and white, the standard in the sport) with a manual punch attached
  • Flagging tape on stakes or branches, labeled with codes
  • Laminated cards on stakes or posts

The important thing is that each checkpoint has a unique code (a letter or number) that students can record to prove they were there.

Confirmation Methods​

Letter Codes (Simplest)​

Each checkpoint has a letter written on it. Students carry a scorecard and write the letter in the correct box. The leader checks scorecards against the all-checkpoints map after the activity.

This is the default method in the curriculum. It requires no special equipment.

Stickers​

Place a sheet of small stickers at each checkpoint. Students take one sticker and place it in the corresponding box on their scorecard. Easy to verify at a glance.

Clothespins​

Students collect a clothespin from each checkpoint and clip it to their scorecard or a string. Used in Clothespin-O for younger students. Tangible and satisfying.

Manual Punch​

A small pin punch attached to each checkpoint flag. Students punch a hole in the correct box on their card. This is the traditional orienteering method and costs about $10 per checkpoint from orienteering supply retailers.

Answer Key (for Manual Punches)​

When using pin punches, prepare a master answer key before the session. The key is a punch card with the correct punch pattern already stamped in each box, in the correct order for each course. When participants finish, hold their card next to the key to check that the patterns match. This is especially important for point-to-point courses where the sequence matters.

Electronic Timing​

Students carry a timing card (SI card) and tap it against an electronic box at each checkpoint. The system records the time and verifies the correct sequence automatically. See Electronic Timing for details.

Night-O Controls (DIY Recipe)​

For evening or low-light orienteering events, you can make reflective checkpoint markers:

Materials:

  • 1-inch internal diameter PVC pipe
  • 4-inch wide reflective tape
  • Nylon cord for hanging
  • Punch device
  • PVC pipe cutter

Assembly:

  1. Wrap reflective tape around the pipe before cutting
  2. Cut pipe into 7-inch lengths using a PVC cutter
  3. Drill holes for cord attachment

The punch stores inside the pipe, making the marker both functional and visible in the dark.
