Some American states are dealing with teacher shortages by lowering the requirements to become public school teachers. Education Week and the Education Commission of the States found that 12 states either recently changed or are considering changing rules surrounding teacher certification. In some states, a college degree is not even required to become a teacher. Others are considering making it easier to pass a teacher exam. The cause and extent of the shortages in the United States are widely debated. But the National Education Association (NEA), an organization representing teachers, says that schools are facing a shortage of 300,000 teachers and school workers. And in a study of school officials released by Education Week last year, 40 percent said teacher shortages were either “very severe” or “severe.” And the pandemic worsened the problem. States are hoping that by making it easier to become a teacher, more people will enter the profession. But critics say the plans will put unprepared and unqualified teachers into classrooms. Teacher certification is done on a statewide, rather than a national level. Requirements vary, but certification requires at least a college degree, and sometimes an advanced degree, like a master's or higher. It also requires completion of a state-approved teacher education program and the passage of a teacher exam.
