The history of learning to read dates back to the invention of writing during the 4th millennium BC. Concerning the English language in the United States, the phonics principle of teaching reading was first presented by John Hart in 1570, who suggested the teaching of reading should focus on the relationship between what is now referred to as graphemes (letters) and phonemes (sounds).

In the colonial times of the United States, reading material was not written specifically for children, so instruction material consisted primarily of the Bible and some patriotic essays. The most influential early textbook was The New England Primer, published in 1687. There was little consideration given to the best ways to teach reading or assess reading comprehension.

Phonics was a popular way to learn reading in the 1800s. William Holmes McGuffey (1800–1873), an American educator, author, and Presbyterian minister who had a lifelong interest in teaching children, compiled the first four of the McGuffey Readers in 1836.

The whole-word method was introduced into the English-speaking world by Thomas Hopkins Gallaudet, the director of the American School for the Deaf. It was designed to educate deaf people by placing a word alongside a picture. In 1830, Gallaudet described his method of teaching children to recognize a total of 50 sight words written on cards. Horace Mann, the Secretary of the Board of Education of Massachusetts, U.S., favored the method for everyone, and by 1837 the method was adopted by the Boston Primary School Committee.

By 1844 the defects of the whole-word method became so apparent to Boston schoolmasters that they urged the Board to return to phonics. In 1929, Samuel Orton, a neuropathologist in Iowa, concluded that the cause of children's reading problems was the new sight method of reading. His findings were published in the February 1929 issue of the Journal of Educational Psychology in the article "The Sight Reading Method of Teaching Reading as a Source of Reading Disability".

The meaning-based curriculum came to dominate reading instruction by the second quarter of the 20th century. In the 1930s and 1940s, reading programs became very focused on comprehension and taught children to read whole words by sight. Phonics was taught as a last resort.

Edward William Dolch developed his list of sight words in 1936 by studying the most frequently occurring words in children's books of that era. Children are encouraged to memorize the words with the idea that it will help them read more fluently. Many teachers continue to use this list, although some researchers consider the theory of sight word reading to be a "myth". Researchers and literacy organizations suggest it would be more effective if students learned the words using a phonics approach.

In 1955, Rudolf Flesch published a book entitled Why Johnny Can't Read, a passionate argument in favor of teaching children to read using phonics, adding to the reading debate among educators, researchers, and parents.

Government-funded research on reading instruction in the United States and elsewhere began in the 1960s. In the 1970s and 1980s, researchers began publishing studies with evidence on the effectiveness of different instructional approaches. During this time, researchers at the National Institutes of Health (NIH) conducted studies that showed early reading acquisition depends on the understanding of the connection between sounds and letters (i.e. phonics). However, this appears to have had little effect on educational practices in public schools.

In the 1970s, the whole language method was introduced. This method de-emphasizes the teaching of phonics out of context (e.g. reading books), and is intended to help readers "guess" the right word. It teaches that guessing individual words should involve three systems (letter clues, meaning clues from context, and the syntactical structure of the sentence). It became the primary method of reading instruction in the 1980s and 1990s. However, it is falling out of favor. The neuroscientist Mark Seidenberg refers to it as a "theoretical zombie" because it persists despite a lack of supporting evidence. It is still widely practiced in related methods such as sight words, the three-cueing system and balanced literacy.

In the 1980s, the three-cueing system (the searchlights model in England) emerged. According to a 2019 survey 75% of teachers in the United States teach the three-cueing system. It teaches children to guess a word by using "meaning cues" (semantic, syntactic and graphophonic). While the system does help students to "make better guesses", it does not help when the words become more sophisticated; and it reduces the amount of practice time available to learn essential decoding skills. Consequently, present-day researchers such as cognitive neuroscientists Mark Seidenberg and professor Timothy Shanahan do not support the theory. In England, synthetic phonics is intended to replace "the searchlights multi-cueing model".

In the 1990s, balanced literacy arose. It is a theory of teaching reading and writing that is not clearly defined. It may include elements such as word study and phonics mini-lessons, differentiated learning, cueing, leveled reading, shared reading, guided reading, independent reading and sight words. For some, balanced literacy strikes a balance between whole language and phonics. Others say balanced literacy in practice usually means the whole language approach to reading.Reading at the Speed of Light: How we Read, why so many can't, and what can be done about it, 2017, p. 248, Mark Seidenberg According to a survey in 2019, 68% of K–2 teachers in the United States practice balanced literacy. Furthermore, only 52% of teachers included phonics in their definition of balanced literacy.

In 1996, the California Department of Education took an increased interest in using phonics in schools. And in 1997 the department called for grade one teaching in concepts about print, phonemic awareness, decoding and word recognition, and vocabulary and concept development.

By 1998, in the U.K. whole language instruction and the searchlights model were still the norm; however, there was some attention to teaching phonics in the early grades, as seen in the National Literacy Strategies.

21st century

Beginning in 2000, several reading research reports were published: 2000 – The National Reading Panel (U.S.) that identified five ingredients of effective reading instruction: phonemic awareness, phonics, fluency, vocabulary and comprehension. 2005 – The Australian report on Teaching reading that supports the use of systematic phonics. 2006 – The United Kingdom Independent review of the teaching of early reading (Rose Report 2006) that supports systematic synthetic phonics.

In Australia, the 2005 report, Teaching Reading, recommends teaching reading based on evidence and teaching systematic, explicit phonics within an integrated approach. The executive summary says "systematic phonics instruction is critical if children are to be taught to read well, whether or not they experience reading difficulties". , The State Government of Victoria, Australia, publishes a website containing a comprehensive Literacy Teaching Toolkit including effective reading instruction, phonics, and sample phonics lessons.

In Scotland a seven-year study (the Clackmannanshire Report) was published in 2005. It compared analytic phonics with synthetic phonics and advantaged students with disadvantaged students. The report found that, using synthetic phonics children from lower socio-economic backgrounds performed at the same level as children from advantaged backgrounds in primary school (whereas with analytic phonics teaching, they did significantly less well.); and boys performed better than or as well as girls. A five-year follow-up of the study concluded that the beneficial effects were long-lasting, in fact the reading gains increased. Subsequently, Education Scotland concluded that explicit, systematic phonics programs, usually embedded in a rich literacy environment, give an additional four months progress over other programs such as whole language, and are particularly beneficial for young learners (aged 4–7). There is evidence, though less secure, that synthetic phonics programs may be more beneficial than analytic phonics programs; however, it is most important to teach systematically.

Until 2006, the English language syllabus of Singapore advocated "a balance between decoding and meaning-based instruction […] phonics and whole language". However, a review in 2006 advocated for a "systematic" approach. Subsequently, the syllabus in 2010 had no mention of whole language and advocated for a balance between "systematic and explicit instruction" and "a rich language environment". It called for increased instruction in oral language skills together with phonemic awareness and the key decoding elements of synthetic phonics, analytic phonics, and analogy phonics.

In 2007 the Department of Education (DE) in Northern Ireland was required by law to teach children foundational skills in phonological awareness and the understanding that "words are made up of sounds and syllables and that sounds are represented by letters (phoneme/grapheme awareness)". In 2010 the DE required that teachers receive support in using evidence-based practices to teach literacy and numeracy, including a "systematic programme of high-quality phonics" that is explicit, structured, well-paced, interactive, engaging, and applied in a meaningful context.

In 2008, the National Center for Family Literacy, with the National Institute for Literacy, published a report entitled Developing Early Literacy. It is a synthesis of the scientific research on the development of early literacy skills in children ages zero to five as determined by the National Early Literacy Panel that was convened in 2002. Amongst other things, the report concluded that code-focused interventions on the early literacy and conventional literacy skills of young children yield a moderate to large effect on the predictors of later reading and writing, irrespective of socioeconomic status, ethnicity, or population density.

In 2010 the Common Core State Standards Initiative was introduced in the United States. The English Language Arts Standards for Reading: Foundational Skills in Grades 1–5 include recommendations to teach print concepts, phonological awareness, phonics and word recognition, and fluency.

In the United Kingdom, a 2010 government white paper contained plans to train all primary school teachers in phonics. The 2013 curriculum has "statutory requirements" that, amongst other things, students in years one and two be capable in using systematic synthetic phonics in regards to word reading, reading comprehension, fluency, and writing. This includes having skills in "sound to graphemes", "decoding", and "blending".

In 2013, the National Commission for UNESCO launched the Leading for Literacy project to develop the literacy skills of grades 1 and 2 students. The project facilitates the training of primary school teachers in the use of a synthetic phonics program. From 2013 to 2015, the Trinidad and Tobago Ministry of Education appointed seven reading specialist to help primary and secondary school teachers improve their literacy instruction. From February 2014 to January 2016, literacy coaches were hired in selected primary schools to assist teachers of kindergarten, grades 1 and 2 with pedagogy and content of early literacy instruction. Primary schools have been provided with literacy resources for instruction, including phonemic awareness, word recognition, vocabulary manipulatives, phonics, and comprehension.
