CVI Explained

Hallways, stairs, cafeteria, PE and recess

For many students with CVI, the hardest parts of the school day happen outside the classroom, where crowds, noise, movement and new places pile up. The fixes are small. Leave a minute early, put bright tape on step edges, keep the same seat and route, name a buddy, and describe what's happening instead of pointing.

Hallways

What goes wrong: Crowds, noise and people moving fast. The student may bump into people, freeze, or arrive at class worn out.

  • Let them leave a few minutes before the bell, before the halls fill up.
  • Use the same route every day, with landmarks: “Turn left at the red fire door.”
  • Pair them with a named buddy, not “someone.”

Stairs, steps and curbs

What goes wrong: Some students with CVI don’t see the lower part of their view well, so steps and edges can seem to vanish. Patterned floors and shadows add to it.

  • Put bright tape on the edge of each step, at the top and bottom, and on the rails.
  • Say it before they reach it, and don’t rush them: “Five steps down, rail on your right.”

Cafeteria

What goes wrong: It’s the loudest, busiest room in the building. Noise can switch vision down, and a full tray is a jumble.

  • Let them go in before the rush.
  • Keep the same seat every day, facing away from the busiest part of the room.
  • In line, name the choices. At the table, name where things are: “Sandwich on the left, milk at the top.”
  • Let them wear noise-canceling headphones if they want to.

Finding friends and a seat

What goes wrong: Many students with CVI can’t pick out faces, especially in a crowd. They may walk past a friend and look rude.

  • Teach classmates to say their own name: “Hi, it’s Ava.”
  • Describe by color and place: “Ava’s at the end of the table, in a green coat.”
  • A seat that never changes lets friends find them too.

PE and ball games

What goes wrong: Fast balls and running players are hard to see and judge. Things can seem to appear from nowhere.

  • Use a big, bright ball, a ball with a bell, or roll it instead of throwing.
  • Say the name before you pass: “Sam, ball coming to you, rolling.”
  • Keep them out of the middle of fast games, and mark boundaries with bright cones.
  • Expect tired vision after PE. Don’t schedule a test right after.

The playground

What goes wrong: Swings, running kids and wide open space with few landmarks. Many students stay at the edges.

  • Walk the playground when it’s empty first. Let them touch the equipment.
  • Point out the swings in words, and keep a clear path away from them.
  • Set a meeting spot: “If you lose us, go to the red bench.”

Assemblies and events

What goes wrong: A new or dark room, loud sound, crowds, and a stage far away.

  • Visit the room when it’s empty, and arrive before the crowd. Sit on the aisle.
  • Have an adult quietly describe what’s happening on stage.
  • Agree on a quiet place they can go if it’s too much.

Fire drills

What goes wrong: A sudden loud alarm, a rushing crowd, and a route they don’t use every day.

  • Walk the exit route with them alone, when the halls are empty.
  • Name one adult in the emergency plan who goes to the student.
  • If the school allows it, tell them before a planned drill.

The bus

What goes wrong: A crowded curb, buses that look alike, a high step, and a bus that may move before they sit.

  • Walk them out early, by the same route, to the same spot.
  • Have the driver say their name, and keep the same seat near the front.
  • Ask the driver to wait until the student is seated before pulling away.

Who can help

The student’s orientation and mobility (O&M) specialist can teach these routes. For the classroom, use the classroom checklist.

Common questions

Why does the student seem fine in class but struggle in the hallway?
A classroom is familiar and fairly still. A hallway adds crowds, noise and fast movement all at once, which is the hardest mix for many students with CVI.
Who teaches a student to get around school safely?
An orientation and mobility (O&M) specialist. If the student has one, ask them to walk the hard routes with you. If not, ask the IEP team about an O&M evaluation.
