The Assessment Completion Time Report is one of three new reports in Questionmark Analytics. Here are the basics:
What it does: The assessment completion time report graphically monitors how long, on average, it took each participant to complete an assessment in relation to  his or her overall score.  For example, someone who took very  little time to complete the assessment  but achieved a very high score would be flagged. Might this person have had prior knowledge of the exam (e.g., prior exposure to the answer key)? On the flip side, someone who took a very long time to take the assessment  but scored very low would be flagged, too. Might this person have been memorizing questions (i.e., taking exam content to sell to other test takers)?
Who should use it: This report provides valuable test security information for those administering medium/high stakes tests. It can also be used to help determine whether the allotted test taking time window is sufficient for most participants.
How it looks: The scatterplot shows the assessment mean for each participant (X-axis) plotted by the assessment completion time for each participant (Y-axis). Clusters of participants that stand out as having extreme combinations of assessment score and assessment completion time are evident in the scatter plot (e.g., participants with short completion times and high assessment scores would stand out in the lower right section of the graph).
Below  the scatter plot is a table that lists participants that are flagged as having suspicious combinations of assessment score and assessment completion time. This list can be useful in conducting an investigation of what happened in a given context.  Click here to learn more about Questionmark Analytics.
