A schedule on the wall that nobody looks at is decoration. The difference between decoration and a tool a child actually uses is almost entirely in three choices.
Photos of the real place or the real person are the fastest read for a child who is not yet reading words — a photo of their actual classroom beats a generic icon of a classroom every time. Icons work once a child has learned to generalise a symbol. Words work once they read. Most families end up mixing all three on one schedule, and that is fine: the schedule's job is to be understood at a glance, not to be consistent in style.
A schedule with every transition of the day on it is accurate and unusable. Start with the three or four moments that cause the most friction — leaving the house, the handoff at drop-off, the return home — rather than mapping the entire day from the first try. Add to it once the first four are working, not before.
A schedule by the front door is checked on the way out. The same schedule on a bedroom wall is checked never. If the hard moment is leaving the house, the schedule lives by the shoes. If it is bedtime, it lives by the bed. Match the location to the friction, not to where it looks tidiest.
No. A photo taken on your phone and printed, or a drawn stick figure, works as well as a commercial set. What matters is that your child recognises it, not how polished it looks.
Narrate it out loud the first several times you use it, standing next to your child and pointing as you go, rather than expecting it to work unattended from day one. It becomes automatic after repetition, not after installation.
If your child asks "what's happening next" often, resists transitions, or seems calmer with warning than without, a visual schedule is worth trying regardless of any diagnosis. You do not need permission from anyone to try it.
