Technical Notes - Bandwidth Footprint Analysis

At this time there are no detailed metrics established for footprint analysis. We will be reporting these when available.

However, at this time, the downstream estimate for simple questions is 40-50 Kb per question. Questions with larger graphics or text passages and questions (e.g., English), can be 100 Kb or higher. Interactive items downstream estimate is between 20-70Kb. Upstream footprint for most test questions is very small, but interactive items could equal the amount of the download or greater.
