In the United States, for example, there are more than 1,500 different teacher-preparation programs. The range in quality is wide. In Singapore and Finland only one academically rigorous teacher education program is available for those who desire to become teachers. Likewise, neither Canada nor South Korea has fast-track options into teaching, such as Teach for America or Teach First in Europe. Teacher quality in high-performing countries is a result of careful quality control at entry into teaching rather than measuring teacher effectiveness in service.
In recent years the “no excuses”’ argument has been particularly persistent in the education debate. There are those who argue that poverty is only an excuse not to insist that all schools should reach higher standards. Solution: better teachers. Then there are those who claim that schools and teachers alone cannot overcome the negative impact that poverty causes in many children’s learning in school. Solution: Elevate children out of poverty by other public policies.
