The development of an achievement test involves a systematic process to ensure its validity and reliability. Here are the key steps:
Step-by-Step Guide to Achievement Test Development
The process is designed to build a test that accurately measures the intended learning outcomes:
-
Establish Need and Purpose:
- This initial phase defines why the achievement test is needed and what it aims to measure.
- For example, is it to assess student learning at the end of a unit, to evaluate program effectiveness, or for placement decisions?
- The reference highlights that understanding this need is fundamental.
-
Delineate the Domain:
- Clearly define the specific subject area or knowledge and skills the test will cover.
- This includes identifying the boundaries of what should and should not be included in the test content.
- For example, will it be focused only on specific topics within a math curriculum?
-
Develop Specific Objectives and Content Standards:
- Translate the broad domain into measurable learning objectives.
- These objectives should align with established educational standards or curriculum guidelines.
- They ensure the test content is relevant and accurately measures what students are expected to know and be able to do.
- Example: "Students should be able to calculate the area of a rectangle" could be an objective within a geometry unit test.
-
Decide on Item and Test Specifications:
- Determine the type of test items (e.g., multiple-choice, essay, performance tasks).
- Decide on the test format, length, and estimated costs of development and administration.
- Consider the practical constraints, such as time limits for testing, scoring methods, and resource availability.
-
Develop Items, Tasks, and Scoring Guides:
- Create the actual questions and tasks based on the specified objectives and content standards.
- Develop detailed scoring guides or rubrics to ensure consistent and objective evaluation of student responses.
- This step is critical for the validity and reliability of the test.
-
Conduct Item/Task Review:
- A crucial phase involving a thorough review of test items.
- This review includes:
- Editorial Check: Ensuring clarity, grammatical correctness, and appropriate language.
- Appropriateness: Verifying that items are suitable for the intended test-takers.
- Alignment: Confirming each item aligns with the stated learning objectives and content standards.
- Sensitivity Review: Addressing potential biases or unfairness in the items due to gender, culture, or other factors.
Summary Table of Steps
| Step | Description |
|---|---|
| 1. Establish Need and Purpose | Define why the test is needed and what it will measure. |
| 2. Delineate the Domain | Identify the specific subject area covered by the test. |
| 3. Develop Objectives and Content Standards | Establish measurable learning objectives and align them with curriculum. |
| 4. Decide on Test Specifications | Determine the format, item types, length, and costs. |
| 5. Develop Items, Tasks, and Scoring Guides | Create test questions and develop scoring rubrics. |
| 6. Conduct Item/Task Review | Review the test for clarity, alignment, appropriateness, and fairness. |
These steps ensure a well-constructed achievement test that provides accurate and meaningful data about student learning. By following these steps, educators can create effective tools for assessing and improving instruction.
