Like all components, EI’s are rated and scored. The rating is based upon the number of data element types (DET’s) and the file types referenced (FTR’s). DET’s and FTR’s are discussed earlier. The table below lists both the level (low, average or high) and appropriate score (3, 4 or 6).
| Files Type Referenced (FTR) | Data Elements (DETs) | ||
|---|---|---|---|
| 1-4 | 5-15 | Greater than 15 | |
| Less than 2 | Low (3) | Low (3) | Average (4) |
| 2 | Low (3) | Average (4) | High (6) |
| Greater than 2 | Average (4) | High (6) | High (6) |
