This chapter addresses the art of formulating and writing SMART outcomes – long- and short-term – with the aim that children and young people have specific, achievable and realistic outcomes that enable and support the development of their decision-making ability, likewise facilitating preparation for adulthood. The quote at the beginning of the chapter is the SEND Code of Practice’s definition of what is meant by ‘outcome’. Additionally, the same paragraph indicates that an outcome describes how the individual will benefit from the education or training intervention. The phrase ‘relevant and purposeful’ is used in the SEND Code of Practice to describe the actions taken by education institutions in identifying, assessing and meeting children and young people’s special educational needs. The acronym SMART has some slightly different variations for the meaning of ‘A’, ‘R’ and ‘T’, but the ones adopted by the SEND Code of Practice are specific, measurable, achievable, realistic, time-bound.
