As children grow, they can develop issues with how they process sensory information from their surroundings. The symptoms of these issues may change over time. So that you can identify these signs and differentiate them from normal childhood behavior, Understood.org has created this graphic. It outlines the different issues you might see as a child progresses through the different stages from a baby to a preschooler, through grade school and middle school, and finally into high school. Sensory issues can vary on a wide spectrum. For example, on one end of the spectrum, you might see that the child does not want to be held. At the other end of the spectrum, you might see that the child constantly needs to touch people or objects. As the child grows older, these issues become more complex.

Get your free personalized learning roadmap
You describe what you see at home. We turn it into a plan you start this week.
- Answer 5 short questionnaires about what you already notice, 30–45 minutes at your own kitchen table
- Your child sits no test and gets no score: nothing to schedule, nothing for them to dread
- You do the answering, the AI does the writing, and a person reviews it before it reaches you
- Access all 40+ courses instantly: reading, math, focus, processing and more, with new ones added regularly
Why we use AI, plainly: it writes from a knowledge base our team maintains and audits. We work through it line by line and pull anything the evidence stops supporting. The roadmap you get on Tuesday reflects what we corrected on Monday, and a human still reads it before you do.
Your school district must evaluate your child free of charge if you ask in writing, whatever your income and whatever the outcome (US, 34 CFR 300.111 and 300.301(b)). That route takes time and answers a different question than you do. This one starts today, from what you already know.
Your answers stay yours. We do not sell your personal information, and we do not hand identifiable assessment data to outside AI companies to train their models.
A screener is a starting point, not a diagnosis. If your child might need formal accommodations (an IEP or 504 plan), or you suspect a vision, hearing or medical cause, pursue a professional evaluation too. That is the only route to those supports.
