Book excerpt: This third edition of the Head of Department's Pocketbook will support middle leaders in both primary and secondary schools in carrying out their jobs confidently and efficiently. Authors Brin Best and Will Thomas know from experience that managing diverse teams in a climate of inflated performance expectations is no easy task. They devote a section of the Pocketbook to leadership and management, encompassing vision, goals and creativity, as well as challenging adult behaviours, up-skilling, influencing and motivating colleagues. A later chapter called 'Raising Student Achievement' looks at excellence in the classroom and includes material on enriching and supporting learning, data use and lesson planning. Effective documentation and raising the profile of your department or curriculum area are also explored. Whether you're new to middle leadership or a seasoned hand, you'll find the self-evaluation checklist at the end of the book a useful professional development tool.
