Your child’s state reading grade and what the national data show aren’t always the same number. Here are the questions parents ask most about the gap — and what to do about it.

Common questions

My child gets good grades in reading at school. Why would I use a different test?

State reading grades and national benchmarks often measure different things. In most states, the 2024 NAEP data showed proficiency rates fifteen or more percentage points below what state tests reported. A nonsense-word decoding check measures pure phonological skill that context-friendly state tests don’t isolate. It takes five minutes and costs nothing — and if the school grade and the decoding score agree, that’s reassuring information too.

What does a low decoding score actually mean?

It points to difficulty with phonological processing — mapping sounds onto letter combinations — which is the core of dyslexia as defined by the International Dyslexia Association’s 2025 update. It’s a reason to look further, not a final answer. Attention, working memory, and auditory processing also affect how a child reads, so treat a low score as a compass bearing: it tells you which direction to investigate, not the full map of what’s happening.

Is this a diagnosis of dyslexia?

No. The Reading Guru’s screener is a screening tool, not a clinical diagnostic test. A screener is a starting point — it identifies risk and tells you which skills to watch. For formal accommodations such as an IEP or 504 plan, or if you suspect a vision, hearing, or medical cause, a professional evaluation is the route to those supports.

What should I do if the school report and this test disagree?

Bring both to your child’s teacher. A specific decoding accuracy score is a far stronger conversation-starter than a general concern. You can also request a school-based evaluation at no cost — federal law (IDEA) requires schools to evaluate children suspected of having a learning disability. A professional evaluation gives you the full picture and opens the door to formal accommodations if needed.
