This book provides the basics of student self-assessment and implementation challenges, and it offers practical solutions and examples for navigating the use of student self-assessment in various subject disciplines in primary schools, secondary schools and higher education.It provides an informed approach for educators to understand the complexities and subtleties involved in implementing self-assessment, and how this might include and impact on teachers and students. Involving students in assessment is not a new idea nor is student self-assessment a new assessment tool in schools.Despite the advantages and the necessity for including it in our pedagogic processes explicitly, the use of student self-assessment has been far from commonplace and consistent in classrooms, schools and universities.This book makes clear the choices of what, how and why student self-assessment is important and usable in the classroom. This book is designed for educators at different levels, and educational researchers.It will provide food for thought for pre- and in-service teachers and school leaders who are interested in nurturing independent and self-directed learners by involving students in the assessment process and maximising student learning through the use of student self-assessment.
