It’s not quite the “Mississippi Miracle,” but California’s reading scores have been inching upwards since the state poured billions into changing the way students learn to read. A shortage of literacy coaches, however, may be preventing students from improving even more.

In 2013, before California overhauled its literacy program in K-12 schools, the state ranked 47th nationally for fourth grade reading skills on the National Assessment of Educational Progress, known as the Nation’s Report Card. Only 27% of students scored “proficient” or “advanced” on the reading test, given every two years to students across the country.

The following year California released a new English language arts framework that encourages schools to focus on phonics, vocabulary and other nuts-and-bolts methods when teaching children to read. Phonics-based instruction won’t become mandatory until next year, but most schools have been gradually adopting the method.

Next came new curriculum materials, a dyslexia screener and updates to teacher credential programs. The state also expanded transitional kindergarten and implemented new guidelines for English learners.

But perhaps the biggest literacy investment came in 2023 with $500 million in grants set aside for schools to hire literacy coaches and take other steps to boost reading skills. The coaches – typically, former classroom teachers with extra training in reading – work directly with teachers to help them effectively teach children to read. Last year the state added $215 million, and the most recent budget includes an additional $350 million for literacy coaches.

Mississippi, whose reading scores went from 49th in the country in 2013 to 9th in 2024, partially credits the turnaround to literacy coaches and other teacher training tactics. Mississippi’s reading framework is similar to California’s, but Mississippi invested heavily in training teachers to implement it, while California rolled out its training program over several years…
