Alberta is not alone. Many top-performing education systems limit the number of teacher training options to a few high-quality programs. And Kentucky is not unusual within the United States, where most states have dozens of teacher training programs available with vastly different levels of rigor. Unlike in the U.S., universities in top-performing countries are not trying to prepare a large number of teachers who will enter and leave the profession quickly. They are investing in individuals who will generally stay in the profession for a substantial career. For more on how some of the best education systems in the world prepare and train teachers, see the “Preparing Profession-Ready Teachers” policy brief from CIEB’s Empowered Educators study.
