            <div>Dear Andrew,</div>
            <div> </div>
            <div>I’ve been working through some final checks of the
              three CCA assessments on our online system over the past
              week or two. While checking the sample reports generated,
              I found that randomly clicking on the buttons in the
              assessment was generating ‘Formal’ stage results.
              Considering that respondents must respond to each item, do
              you have any information about the validity of the results
              or is there a way of administrators being able to
              determine if a test taker was guessing the answers?</div>
            <div>We thought that if the items have been linked to the
              stages (for example, if items 1 to 10 are linked to the
              Primary stage, items 11 to 16 to the Concrete stage), then
              it may be possible to provide a second page to the report
              showing the client’s responses on a scale, which would
              indicate at what stage they began responding incorrectly.</div>
            <div>I look forward to hearing your thoughts on this.</div>
            <div> </div>
            <div>Best wishes,</div>
            <div>Amanda</div>
