Helping children and adults to better understand the sounds and spellings in English words.

THRASS (UK) LIMITED publishes the English Spelling Chart Resources (through www.thrass.co.uk) and is also responsible for training teachers in Europe, the Middle East, South America, Central America (and the Cayman and Caribbean Islands), the USA, Central Asia and Africa. It also publishes and oversees the video programmes ‘English Sounds Code. THE ESC VIDEOS.’ and 'English Sounds Code. Where's the Sound?' through the YouTube Playlists of the same name. The teaching videos help children and adults (as individuals, or in pairs, groups or classes) to better understand the sounds, spellings (keyspellings and non-keyspellings), syllables, consonant blends and rhymes in English words. For pupils/students, student teachers, teachers and parents, the videos and pdf downloads are a great way to learn or revise the building blocks of English words. The English Sounds Code is a numeric code that uses the sound-box numbers on the English Spelling Chart.

The resources are for learners of all ages and abilities, including young children (and their parents!) and those learning English as an additional language. They are used to develop speaking and listening skills, vocabulary and general knowledge. They are also used to teach learners to read words by sight and to focus on the meaning, and to work out the right sounds when they cannot read a word, and visualise and name the right letters when they cannot spell a word (through using a thorough knowledge of the keyspellings and non-keyspellings of English). The resources are used in nurseries, primary and secondary schools, and adult centres with individuals, groups and classes (including deaf and blind learners, those with dyslexia, learning or speech difficulties, and those recovering from memory loss as a result of brain injury). The resources are also used by workers and managers in businesses.

The foundations for the English Spelling Chart Resources were initially conceived by British Educational Psychologist, Alan Davies, using the International Phonetic Alphabet.

A copy of the original work was lodged with Stationers Hall Registry, London, England in 1989. The first charts and resources were published in England in 1992 and 1994, under the programme title 'THRASS' - Teaching Handwriting Reading And Spelling System (1992), Sequence (1994) and Skills (1996).

In 1995, Alan was joined by Australian Denyse Ritchie and together they created and designed the THRASS professional development courses and various THRASS resources. Since April 2005, the courses and resources have been developed and managed in territories. THRASS UK, overseen by Alan Davies and Hilary Davies, now publishes all previous and new titles under the THRASS English Spelling Chart Resources umbrella.

THRASS (UK) LIMITED is licensed to serve customers in Europe, the Middle East, South America, Central America (including the Caribbean), the USA, Central Asia (Pakistan, Afghanistan, Turkmenistan, Uzbekistan and Kazakhstan) and Africa (excluding South Africa, Lesotho, Swaziland, Botswana and Namibia, which since 2011 have been overseen by Bidvest Paperplus Proprietary Limited).
