It is often desirable to retest a student after the initial assessment, either to monitor progress or because the first assessment was unreliable for some reason (e.g. because the student was unwell, unmotivated or misunderstood the requirements). As explained in Section 1.1.6, due to practice effects, retesting using conventional tests can be problematic and minimum intervals between testing sessions (e.g. 6 or 12 months) are stipulated to try to counter these effects, or parallel forms of the test are used.
Since item content in Lucid Recall is generated at random, practice effects are minimised and consequently there are no stipulated intervals between testing and retesting with Lucid Recall, nor any restrictions on the number of times students may be retested. This is particularly useful when needing to evaluate the impact of intervention over time. Indeed, Lucid Recall has been set up to facilitate retesting. When a student completes all three tests in the Lucid Recall suite a new test record is automatically created so that the program is ready for the student to be retested whenever that may be. When a student has completed the test suite a second time, their results can be viewed in Historical Report format, which displays the results of the last four occasions on which the student was tested.
