Beginning with the 2025–26 school year, California — long one of the last holdouts on universal screening — requires every public school to screen students in kindergarten through second grade for risk of reading difficulties, including dyslexia. For the nation's largest school system, serving roughly one in eight American public-school students, it's a generational shift: reading risk in California is now something schools must look for, rather than something parents must prove.

What does California's screening law require?

Districts were required to select a screener from a state-approved list (selection deadlines passed in summer 2025) and administer it annually to all K–2 students. Schools must notify families of results, and screening must accommodate English learners — a significant design consideration in a state where nearly a third of young students are learning English. The screening requirement sits alongside California's existing dyslexia guidelines and the state's broader literacy initiatives.

How does the screening actually work?

The screeners are short — minutes per child, often one-on-one with a teacher or aide — and measure the early skills that decades of research show predict reading trouble:

  • Phonological awareness — can the child hear and play with the sounds inside words?
  • Letter-sound knowledge — does the child connect letters to the sounds they represent?
  • Rapid automatized naming — how quickly can the child name familiar items, a surprisingly strong predictor of reading fluency?
  • Word and nonsense-word reading (in later screening windows) — can the child apply decoding rather than memorization?

Screening is not a diagnosis, and California's tool is explicitly a risk screener. It sorts children into risk levels so schools can respond early — in kindergarten and first grade, when intervention is dramatically more efficient than remediation in fourth.

What should parents do if their child is flagged?

First: a flag is good news arriving early. It means the system noticed before failure did the noticing. Then ask four questions, in writing if possible:

  1. What intervention will be provided, and starting when? "We'll monitor" is not an intervention.
  2. Who delivers it, with what training, in what group size, for how many minutes per week? Intensity drives results.
  3. How will progress be measured, and when will results be shared with me? Expect a named measure and a schedule, not vibes.
  4. At what point would the school move to a full evaluation? If intervention isn't working, evaluation for special-education eligibility is the next step — and you can request it at any time.

What if the screener says "not at risk" but you're still worried?

Treat the result as a snapshot, not a verdict. Education reporters covering the rollout have cautioned that screening results can be misread in both directions — and a bright child who compensates by memorizing words can pass an early screen while still carrying the phonological weakness underneath. If you see the signs of dyslexia at home — guessing from first letters, spelling that doesn't match sounds, tears at homework — you retain the full legal right to request a comprehensive evaluation in writing at any time, regardless of screening results. Our parent toolbox includes the exact letter.

Common misunderstandings to avoid

  • "The school screened, so they'll handle it." Screening laws in many states have stalled precisely at this hand-off. Stay in the loop on what happens after the flag.
  • "A flag means my child has dyslexia." It means risk. Some flagged children respond quickly to good instruction; others will need evaluation and sustained intervention.
  • "My English-learner child was flagged because of English." Good screeners are designed to distinguish language development from reading risk, but it's fair to ask how your district's screener accounts for multilingual learners.
  • "We missed the window." Screening is annual in K–2, and evaluation rights never expire.

Frequently asked questions

Is the screening a dyslexia diagnosis? No. It identifies risk so schools can act early. Identification of dyslexia comes from a comprehensive evaluation.

Can I see my child's screening results? Yes — schools must notify families, and you can request the detailed results and ask what they mean skill by skill.

Does a flag start special-education timelines? Not by itself. A written parental request for evaluation does — which is why the letter matters. The template is here.
