Performance/Academic Descriptors sample process

performance descriptor sample steps in making

1. Performance Descriptors

2. Understanding the Need for Revision It's essential to ensure that the score ranges assigned to each performance level are fair and accurately reflect the students' achievement. Factors to consider include: Test Difficulty: Is the test overall easy, moderate, or difficult? Item Discrimination: Do the items differentiate between high and low achievers? Student Population: What is the general academic level of the students?

3. Revising the Score Ranges Here are some methods to revise the score ranges:

4. Method 1: Item Analysis Calculate item difficulty: Determine the percentage of students who answered each item correctly. Calculate item discrimination: Assess how well each item differentiates between high and low achievers. Adjust score ranges: Based on the item analysis, modify the score ranges to accurately reflect the difficulty of the test and the performance of students.

5. Method 2: Standard Deviation Calculate the standard deviation: This measures the spread of scores around the mean. Use standard deviation to set cut-offs: Determine the score ranges for each level based on multiples of the standard deviation from the mean.

6. Method 3: Norm-Referenced Approach Compare to a reference group: If available, compare the students' scores to a norm group (e.g., previous years' data, national norms). Set cut-offs based on percentiles: Determine the score ranges based on specific percentiles (e.g., top 25%, next 25%, etc.).

7. Method 4: Expert Judgment Involve subject matter experts: Seek input from teachers or content experts to determine appropriate score ranges. Consider curriculum standards: Align the score ranges with the expectations outlined in curriculum standards.
