Leadership is a critical aspect of all social endeavors. In schools, talented leadership is essential to student achievement. School leadership impacts all facets of education: teacher motivation, shaping the conditions and the environment in which teaching and learning occurs, and interaction with the broader community. A large scale six-year study reported by Louis et al (2010) covering 180 schools in 43 school districts in the US found that there is no single case of a school improving its student achievement record in the absence of skilled school leadership.
In many school systems, effective school leadership is far from the norm. It is often simply assumed that school leaders, irrespective of capacity, will discharge responsibilities and initiatives assigned to them. Moreover, programs to prepare and or support school leaders are either lacking or ineffective.
A few weeks ago, education policy makers and data analysts around the world were glued to their laptops when the Organization for Economic Cooperation and Development (OECD) published the results of PISA 2015. More than half a million students – from 72 countries and economies representing 28 million 15 year-olds – had taken the test. PISA, an international assessment administered every three years, measures the skills of students in applying their knowledge of science, reading, and mathematics to real life problems. PISA is one of the most influential international student assessments, which provides a rich set of information on the systems strengths and weaknesses, supports development of effective policies – and at the same time, benchmarks country's achievements vis a vis other participating countries.
