The Reading Wars Veteran Who is Now Winning

Louisa Moats, an 81-year-old researcher, has become an unlikely figurehead in the ongoing debate over how to teach children to read. Her training program, Language Essentials for Teachers of Reading and Spelling (LETRS), developed decades ago, is now widely adopted by states seeking to combat declining literacy rates across the U.S.

Moats has long advocated for a structured approach to reading instruction, emphasizing the explicit teaching of phonics, phonology, morphology, and orthography. This approach contrasts with earlier philosophies, such as whole language and balanced literacy, which suggested that children could learn to read more intuitively through context and exposure to engaging materials.

Interest in Moats' methods has surged amid a national literacy crisis. According to the 2024 National Assessment of Educational Progress (NAEP), approximately 40% of American fourth-graders have not mastered basic reading comprehension skills, the worst result in two decades. This decline predates the COVID-19 pandemic but was exacerbated by school closures. Concerns are widespread, with educators and researchers noting that a significant portion of young adults are functionally illiterate, and even high school graduates struggle with basic reading tasks.

In response, 42 states and Washington D.C. have enacted science-of-reading laws, typically mandating structured literacy techniques, including phonics instruction. LETRS has become a popular choice for schools to comply with these mandates. The program is known for its rigor, requiring teachers to delve into language theory and cognitive science. It covers detailed aspects of English phonetics, such as 19 vowel sounds and 29 consonant sounds, and explores word structure and spelling patterns.

The program's rollout has been substantial. In 2025, an estimated 700,000 teachers, primarily in lower elementary grades, were enrolled in the 155-hour course. States like Michigan have invested heavily, dedicating $75 million to ensure every reading teacher can complete the training. Moats, who receives royalties from the program, acknowledges the overwhelming attention with a mix of humility and satisfaction.

Moats' journey into literacy education was unconventional. After graduating from Wellesley College, she worked in neuropsychology research and earned a master's degree in learning disabilities from Vanderbilt University. Her early career involved trying to 'cure' learning disabilities, an experience that highlighted the gap between academic theory and classroom reality. A pivotal period at Harvard, under the guidance of linguist Carol Chomsky and reading researcher Jeanne Chall, solidified her understanding of the intricate relationship between language processing and reading acquisition.

She observed that children struggling with reading often failed to grasp the connection between sounds and letters. This led her to believe that effective reading instruction required a deeper understanding of language science than many teachers possessed. By the mid-1980s, she began teaching teachers, encountering alarming deficits in their understanding of reading fundamentals, often rooted in whole-language methodologies.

Moats' work gained further traction through her involvement with a federally funded reading-research network led by G. Reid Lyon. Her role in implementing structured literacy in Washington D.C. schools led to significant improvements. This success contributed to the inclusion of her work in the No Child Left Behind Act's Reading First initiative, which ultimately led to the development of LETRS.

Despite the program's growing influence, earlier evaluations, such as an Institute of Education Sciences report on LETRS, indicated that while teacher knowledge improved, student outcomes did not see a significant boost after a single year of training. Moats contends that a year is insufficient to expect measurable changes in student achievement.

The landscape of reading instruction has been marked by what Moats termed the "reading wars," a conflict between proponents of phonics-based instruction and those favoring whole language or balanced literacy. Lucy Calkins, founder of the Teachers College Reading and Writing Project, was a prominent proponent of balanced literacy, which emphasized contextual learning and access to plentiful books. Moats critically argued in a 2000 essay that simply blending elements of different approaches did not constitute effective instruction.

Parents, particularly those of children with dyslexia, began advocating for more explicit phonics instruction. Mississippi's early adoption of LETRS training for its K-3 teachers, coupled with other educational reforms, coincided with the state's most significant improvement in fourth-grade NAEP reading scores between 2013 and 2019.

Journalist Emily Hanford's 2018 podcast series, "Sold a Story," further amplified concerns about balanced literacy and bolstered the science-of-reading movement. Despite this growing momentum, implementing changes in educational institutions, particularly in higher education, has been a slow and sometimes contentious process.

As LETRS gains wider adoption, some former trainers express concerns about a shift in focus from mission to profit following Lexia Learning's acquisition by a private-equity firm. Meanwhile, ongoing research, including a large randomized study on LETRS's effectiveness, is underway, with results expected in 2029. While some recent national data suggests nascent improvements in reading scores, experts caution that it is too early to declare a definitive turning point.

Experts also emphasize that teacher training alone is not a panacea for the nation's literacy challenges. Issues such as truancy and varying attendance levels also significantly impact student learning. Moats, while seeing her program gain traction, remains focused on ensuring that the core principles of effective reading instruction are deeply understood and implemented, recognizing that literacy is fundamental to cognitive development and learning.
