The Critical Role of Expert Judgment in Cut-Score Setting: A Guide to the Modified Angoff Method

In the realm of standardized testing, determining the passing score or cut score is a crucial task that influences the interpretation of test results. Among the various cut-score setting techniques, the Modified Angoff Method stands out for its use of expert judgment to establish a fair and defensible passing threshold.

The Importance of Subject Matter Experts (SMEs)

At the heart of the Modified Angoff Method lies the valuable input of subject matter experts (SMEs). These individuals, who possess deep knowledge and understanding of the subject matter being tested, play a critical role in providing estimates of item difficulty. Their expertise ensures that the cut score accurately reflects the intended level of mastery for the test.

Considerations for Selecting and Involving SMEs

The selection of SMEs is a key factor in the success of the Modified Angoff Method. When choosing experts, it is essential to consider the following factors:

  • Content expertise: SMEs should have a thorough understanding of the specific subject matter covered by the test.
  • Communication skills: Experts should be able to clearly articulate their judgments and provide detailed explanations for their estimates.
  • Fairness and objectivity: SMEs should be unbiased and free from any potential conflicts of interest.

Involving SMEs in the cut-score setting process typically involves a series of structured interviews or workshops where experts provide their estimates for item difficulty. These judgments are then aggregated and used to calculate the final cut score.

By carefully selecting and involving SMEs, test developers can ensure that the Modified Angoff Method yields a cut score that is both valid and reliable, accurately reflecting the level of proficiency required to demonstrate mastery of the content being tested.

Calculating the Cut Score: The Heart of the Modified Angoff Method

Once subject matter experts (SMEs) have meticulously evaluated each test item, the next crucial step in the Modified Angoff Method is determining the cut score, the threshold that separates passing from failing. This process involves fusing the collective knowledge and judgments of the experts with careful consideration of the test’s difficulty and the desired level of performance.

The cut score is derived from the proportion of items that the SMEs judge to be “passable”. Typically, a panel of SMEs independently assigns each item to one of three categories: “definitely pass,” “definitely fail,” or “uncertain.” The cut score is then calculated as the percentage of items that the majority of SMEs classify as “definitely pass.”

For instance, consider a test with 100 items. If the majority of SMEs deem 60 items as “definitely pass,” the cut score would be 60%, meaning that a test taker who answers 60% or more of the items correctly would be considered passing.

However, the decision on the cut score is not always straightforward. Factors such as the difficulty of the test and the expected performance level of the test takers come into play. If the test is particularly challenging, a lower cut score may be appropriate to ensure that a reasonable number of candidates pass. Conversely, for an easier test, a higher cut score might be necessary to maintain a desired level of proficiency.

Calculating the cut score using the Modified Angoff Method is a delicate balancing act that requires a judicious combination of expert judgment and objective data. By taking into account the SMEs’ insights and considering the test’s characteristics, test developers can establish cut scores that accurately reflect the desired level of competency and ensure fair and meaningful testing.

Benefits and Limitations of the Modified Angoff Method

The Modified Angoff Method stands out as a widely recognized technique for cut-score setting in standardized testing. It relies on the judgments of subject matter experts (SMEs) to estimate the difficulty of each test item, facilitating the establishment of a passing score or threshold for satisfactory performance on the assessment. While this method offers several advantages, it also has its limitations that should be carefully considered.
