Post testing is a method used to evaluate learning or knowledge acquisition after a period of instruction or training.
Based on the provided reference, a post-test is specifically defined as:
"a test given to training participants after the instruction is presented or completed."
In the context of learning and development, post-testing serves as a critical tool to measure the immediate impact of a training program or educational module.
Purpose of Post Testing
The primary purpose of giving a test after instruction is to assess what participants have learned or retained. When used in conjunction with a pre-test (a test given before instruction), post-testing allows trainers and educators to quantify the improvement in knowledge or skills.
As highlighted in the reference:
"Using pre-testing and post-testing can show the percentage of knowledge gained."
This measurement helps determine the effectiveness of the training content and delivery methods.
Post Testing in Practice
Post tests can take various forms depending on the type of instruction and what is being measured. Common examples include:
- Multiple-choice quizzes
- Short answer questions
- Practical demonstrations or simulations
- Problem-solving exercises
Using Pre & Post Tests
The most insightful application of a post-test is comparing its results to those of a pre-test taken by the same participants.
| Assessment | Timing | Purpose |
|---|---|---|
| Pre-Test | Before instruction | Measure baseline knowledge before training. |
| Post-Test | After instruction | Measure knowledge after training. |
By comparing scores, one can calculate the "gain score" or percentage of knowledge improvement. For instance, if a participant scored 40% on a pre-test and 80% on a post-test, they demonstrated a 40% increase in knowledge related to the training topic.
Benefits of Post Testing
- Measures Learning: Directly assesses what participants retained from the instruction.
- Evaluates Training Effectiveness: Provides data points to determine if the training achieved its learning objectives.
- Identifies Knowledge Gaps: Can reveal topics that were not fully understood or covered adequately.
- Supports Program Improvement: Results can inform revisions to training materials or delivery methods.
Post testing is a fundamental component of evaluating educational and training initiatives, providing concrete evidence of learning outcomes.
