Retesting with LASS 8-11
Teachers often ask ‘How soon can a student be retested with LASS 8–11?’ The answer depends on why retesting is being considered. If the teacher has good reason to believe that a given result is not truly indicative of a student’s ability because of some hindrance factor, then retesting can be as soon as is convenient. For example, this would be the case if a student had a cold and could not hear the words, was unwell and not able to concentrate, was excessively nervous, or because there were unexpected distractions in the room. Obviously, efforts should be made to ensure that those hindrance factors have been resolved before retesting.
Retesting will overwrite the student’s previous results .
If the teacher wishes to see if the student has improved as a result of some intervention, then a sensible interval should be allowed before retesting. In general, four months would be recommended as the minimum interval, but this could be less if the teacher had good reason for doing so. Repeated retesting at short intervals is not advisable because under those circumstances any ability or attainment test is likely to show spurious improvements in performance by virtue of practice effects.
