Big Writing is an approach to teaching writing developed by Ros Wilson and marketed by Andrell Education. The aim of Big Writing is to advise schools on how to raise attainment level in speaking, listening and writing. The method is currently used by numerous schools, primarily in the UK but also overseas. The target audience for Big writing are Key Stage 1 and Key Stage 2 students (i.e. those aged 5 to 11), although a slightly adjusted method is also taught that focuses on Foundation stage pupils and is known as 'Big Talk'. Andrell Education claims that Big Writing has proven to be successful in a number of schools, both with teachers and pupils, and points to case studies as evidence of this.
