In looking at the results from prior observations for a learner using a specific form, the system will automatically use a default start date. If you want the start date to be either earlier or later, you will need to change the start date to the appropriate date, then click "View". This will make the new set of results appear in the table.
In the results table, you can click on the "Graph" link under the look-for name in the first column to see a graphical representation of the learner's performance over time on that specific look-for. In the other columns, you can see the result for that look-for on the specified date.
You can also click on the "Evidence" link in the box representing a combination of a date and look-for to see the evidence that was checked during the observation and also to view any attachments that may have been uploaded by the observer related to the look-for.
