Question

Explain the steps of construction of achievement test with example.

Hint:

Group the construction steps into planning, item-writing, and try-out/analysis phases, with a subject example.

Answer 1

Step 1: Understanding the Concept:
An achievement test must be built carefully so that it truly measures what students learned from a specific course, not something else. This is done in defined steps.

Step 2: The steps.
1. Planning: decide the purpose of the test, the subject, and the class level. Example: a test on the chapter "Photosynthesis" for class 10 science.
2. Preparing a blueprint: make a table showing how many questions will come from each topic, and at what difficulty and question-type (MCQ, short answer, etc.), so coverage is balanced.
3. Writing items: write the actual questions based on the blueprint, covering knowledge, understanding, and application of the topic.
4. Arranging items: order questions from easy to difficult, and group similar types together for clarity.
5. Preparing a marking scheme: fix the marks for each question and, for subjective answers, the key points expected.
6. Try-out (administering to a small group): give the draft test to a small sample of students first, to catch confusing questions.
7. Item analysis: review the try-out results to check if questions are of the right difficulty and correctly separate strong and weak students, then revise or drop poor items.
8. Finalising the test: prepare the final, corrected version ready for actual use.

Final Answer:
Planning, blueprint preparation, item writing, arranging, marking scheme, try-out, item analysis, and finalising are the steps, illustrated here with a class 10 "Photosynthesis" achievement test.
