The process used by one researcher in developing an inventory of specific tasks performed by language teachers is described. The objective was to facilitate research on language teachers' jobs in a variety of countries and under differing teaching conditions and to provide job profiles for use in teacher education and by teachers, their unions, administrators, and others concerned with language teaching. The first section of the report describes the methodology of creating a task list. The second section makes observations on underlying models of the teacher's role and responsibilities. The bulk of the report is in the appended lists of tasks derived from teacher interviews. (MSE)
