Until the twentieth century, teachers received relatively little preparation and had little say in terms of their employment. Teacher training consisted of one or two years and some times less at a teacher training college. and teachers had to follow strict rules and regulations concerning their behaviour outside the school. Unorganized and isolated from one another, teachers could be stanmarily dismissed by a board of education.Times have changed. Today, teachers aspire to be professionals with expert knowledge concerning instruction, content and method in their particular fields. In addition they are well organized as a group and have gained greater rights to be judged on their work performance rather than on their behaviour outside school. Often. too, they participate in decision making about work conditions. In many cases, they are forging stronger links with school administrators, university researchers, government officials, and the communities they serve.
