How Does Avant STAMP Individualize Assessment?

Computer-adaptive testing dynamically adjusts the difficulty of test questions based on the test taker’s responses. Unlike fixed-form tests, where every test taker answers the same questions, Avant STAMP tailors the test to the individual’s ability level in real-time. This personalized approach ensures a “more accurate and efficient assessment across the proficiency scale” (Hendrickson, 2007).

How Does It Work? 

Avant STAMP uses a multi-stage adaptive testing (MST) design.

Each Avant STAMP test begins with Intermediate-level questions. As test takers move through the test the questions adjust based on their skill level, becoming more advanced or more novice, depending on their performance.

This adaptive approach enhances measurement precision and improves the test experience. Unlike linear tests, where test takers may encounter questions that feel too easy or too difficult, Avant STAMP keeps the questions at an optimal level, providing a more engaging and accurate assessment.

Integrated Proficiency Tracking

In Avant STAMP, proficiency achieved in the Reading section informs the Writing prompts, and proficiency in the Listening section informs the Speaking prompts.

The Reading score affects Writing prompts, and Listening score affects Speaking prompts.

In the case of Avant STAMP WS, test takers perform a self-evaluation through a series of CAN-DO statements of Reading and Listening to determine the prompt levels for Writing and Speaking. 

Computer-Adaptive vs. Fixed-Form Testing

1. Precision and Efficiency

  • Adaptive Questioning: STAMP adjusts the difficulty of questions based on previous responses, honing in on the test taker’s true ability.
  • Accurate Measurement: By continuously calibrating the test to the individual’s performance, STAMP provides a more precise assessment of their proficiency.

2. Enhanced Test Taker Experience

  • Reduced Test Anxiety: Test takers are less likely to encounter questions that are too difficult or too easy, creating an environment where they are challenged without leading to frustration.
  • Shorter Testing Time: STAMP typically requires fewer questions to accurately assess proficiency, reducing the overall testing time without compromising accuracy.

3. Data-Driven Insights

  • Real-Time Feedback: Immediate results and insights help educators tailor instruction to meet the specific needs of their students.
  • Detailed Reporting: Comprehensive data on individual and group performance allows for informed decision-making and targeted improvements.
