Final answer:
To compute an index score that measures the rate of performance improvement, follow these steps.
Step-by-step explanation:
To compute an index score that measures the necessary rate of performance improvement, you need to establish a baseline and compare it to the current performance level. Here's a step-by-step process:
- Identify the performance indicator you want to measure. For example, if you want to measure the rate of improvement in test scores, you would use test scores as the indicator.
- Choose a time frame for comparison, such as comparing performance at the beginning and end of a school year.
- Calculate the difference between the baseline and current performance for each individual. For example, if a student scored 70 at the beginning of the year and 80 at the end, the difference is 10.
- Calculate the average difference for all individuals.
The index score can be represented as a percentage or on a scale of 1 to 10, depending on your preference. The higher the index score, the greater the rate of performance improvement.
