Studies of teacher use of tests suggest that classroom tests are widely used and standardized test results are rarely used. Previous comparisons of preservice and inservice teachers' attitudes toward assessment suggest few differences. Differences in opinions about the use of classroom and standardized tests were assessed via surveys of three groups: 84 college sophomores beginning a teacher education program; 152 college seniors completing a teacher education program, but without student teaching experience; and 553 inservice teachers in a western state. Significant differences in opinions were found, with inservice teachers having more favorable attitudes than teacher education students toward classroom testing and less favorable attitudes toward standardized testing. This difference may reflect current realities of test use in teachers' and students' lives. Two data tables and a 25-item list of references are included. (SLD)
