Campus Route Planning for a Student with Low Vision and a Power Wheelchair
Devon is a 16-year-old 10th grader with retinopathy of prematurity. His acuity is 20/200 in the right eye, he has no light perception in the left eye, and his visual field is approximately 40 degrees. He uses a power wheelchair and is new to a high school with 2,000 students, five buildings, and active construction that has closed the main sidewalk. His schedule requires travel from the bus loop to four classrooms in three buildings, the cafeteria, and a restroom, with five-minute passing periods. He can drive the wheelchair but gets disoriented after two turns and often asks staff for escorts. His IEP has one weekly 30-minute O&M session. The O&M specialist must decide what to prioritize before the construction ends in eight weeks.
1. What should the O&M specialist prioritize in the eight weeks before construction ends?

The priority is safe, independent route travel, not simply covering every possible destination. First, assess Devon's current wheelchair control, low-vision use, orientation strategies, and route knowledge. Then focus on the highest-frequency, highest-risk routes: bus loop to first period, the three-building class-to-class routes, the restroom, and the cafeteria. Because construction has closed the main sidewalk, the specialist should coordinate with facilities to confirm an accessible alternate route and identify temporary hazards such as barricades, uneven surfaces, and redirected traffic.
Teach one route at a time using segmenting, landmarks, turn counting, auditory cues, and a tactile or large-print map. Practice during passing periods and during quieter times. Increase O&M frequency temporarily rather than relying on one weekly session. Build in a backup route and a self-advocacy plan for asking staff or peers when a path is blocked. The goal by week eight is that Devon can travel his core schedule with minimal prompts and can problem-solve a blocked route.
2. How should the O&M specialist deliver instruction and collect data?

Use a task analysis for each route: exit bus, orient to building, travel segment, turn, locate door, enter, find room. Teach with modeling, co-travel, verbal rehearsal, and a fading prompt hierarchy. Use a tactile map or simplified large-print map, but do not let the map replace real travel. Have Devon 'think aloud' about the next landmark before moving, and teach him to self-correct after a wrong turn rather than waiting for an adult.
Collect data on prompts per route, time to destination, safety errors, self-corrections, wheelchair control, and incidents. Observe at different times of day and in different lighting. Generalize by teaching a new route using the same strategy once the first routes are solid. Data should drive decisions about whether an adult escort is needed for a specific segment, not as a permanent default.
3. A staff member suggests assigning Devon an adult escort all day for safety. Evaluate this proposal.

An all-day escort may reduce immediate risk, but it would also prevent Devon from practicing orientation, route planning, and self-advocacy-skills he needs for transition. It should be used only as a temporary safety net for a specific high-risk segment while instruction continues, not as a blanket solution.
A better response is to fix the environment and teach the route: confirm an accessible construction path, mark hazards, adjust passing time if needed, provide a peer or staff check-in at a single decision point, and fade support as data show improved accuracy. The IEP team should document the rationale, the specific conditions under which support is used, and the criteria for fading it. Independence in a power wheelchair is a realistic and important goal; the O&M specialist should advocate for support that builds skill rather than dependence.
