Expert Advice on Developing Test Questions
Before you begin writing a test, it is very important to consider your purpose i.e. what it is you intend to test. It is also essential to distinguish among the different test types e.g. do you want to test achievement or proficiency or do you want to test diagnostic and/or prognostic skills? Achievement tests are those that test a student’s subject knowledge, e.g., how well he or she understands the material covered on the course they are taking. Proficiency tests are those tests designed to measure a student’s ability in a particular area such as, say, one’s language proficiency. These tests are not specific to any particular course. Diagnostic tests are designed to draw out a learner’s strengths and weaknesses in a given area or field of study.
Prognostic tests are tests that try to predict a student’s performance in a particular subject or on some course, they are taking, e.g., how well they are likely to do. Of course, there are many more categories of exams and tests. The important thing is to choose your methods and techniques very carefully when preparing any of the types of tested described above.
