A diagnostic assessment is a form of pre-assessment where teachers can evaluate students’ strengths, weaknesses, knowledge and skills before their instruction. An identical assessment may be given post-instruction to identify if students have met a course’s required learning objectives. With this form of assessment, teachers can plan meaningful and efficient instruction and can provide students with an individualized learning experience. Written by students, the diagnostic assessment is a tool for teachers to better understand what students already know about a topic when submitted before the start of a course.
A diagnostic assessment refers to an assignment written at the beginning and end of a course. Post-course assessments can be compared with pre-course assessments and can show students’ potential improvement in certain areas. These assessments allow the instructor to adjust the curriculum to meet the needs of current—and future—students.
