T-Score Calculation Order

To correctly sum T-scores and assign final grades, follow this specific sequence:

• C. Develop T-score norms for each test

  This is the crucial first step. Before individual scores can be meaningfully interpreted or converted, established norms (based on a representative sample) must be created for each specific test.

• B. Assign each student a T-score in each of the tests

  Once the norms are developed, you can calculate and assign the appropriate T-score to each student for every test they have completed. T-scores allow for comparison across different tests with varying scales.

• A. Sum the T-score for each student

  If a composite score is needed, sum the individual T-scores obtained by each student across the relevant tests. This step combines performance data from multiple assessments.

• E. Develop final letter-grade standards

  Establish clear criteria and standards that link the summed T-scores (or other derived scores) to specific letter grades (e.g., A, B, C). This involves defining score ranges for each grade.

• D. Assign final grade

  Finally, apply the established letter-grade standards to the summed T-scores to assign the final grade to each student.

Therefore, the correct sequential order is C, B, A, E, D.
