One thing that has struck me is how similar education systems are. Curricula are standardized to fit to international student tests; and students around the world study learning materials from global providers. Education reforms in different countries also follow similar patterns. So visible is this common way of improvement that I call it the Global Educational Reform Movement or GERM. It is like an epidemic that spreads and infects education systems through a virus. It travels with pundits, media and politicians. Education systems borrow policies from others and get infected. As a consequence, schools get ill, teachers don’t feel well, and kids learn less.

GERM infections have various symptoms. The first symptom is more competition within education systems. Many reformers believe that the quality of education improves when schools compete against one another. In order to compete, schools need more autonomy, and with that autonomy comes the demand for accountability. School inspections, standardized testing of students, and evaluating teacher effectiveness are consequences of market-like competition in many school reforms today. Yet when schools compete against one another, they cooperate less.

The second symptom of GERM is increased school choice. It essentially positions parents as consumers empowering them to select schools for their children from several options and thereby promotes market-style competition into the system as schools seek to attract those parents. More than two-thirds of OECD countries have increased school choice opportunities for families with the perceptions that market mechanisms in education would allow equal access to high-quality schooling for all. Increasing numbers of charter schools in the United States, secondary school academies in England, free schools in Sweden and private schools in Australia are examples of expanding school choice policies. Yet according to the OECD, nations pursuing such choice have seen both a decline in academic results and an increase in school segregation.
