The following six case studies illustrate how the results of Rapid can be interpreted, over and above the interpretation automatically provided by the program. It should be emphasised that in all these cases, diagnosis can only be tentative because the information derived from a 15 minute screening program is inevitably limited. Nevertheless, in most cases the information from each of the three subtests in Rapid can help the teacher to understand the nature of the fundamental underlying problems and move forward to effective action without unnecessary delay. In cases where more detailed understanding is sought, the student can be tested on CoPS or LASS 8–11 (as appropriate to the student’s age). For CoPS and LASS 8–11, results from Rapid will automatically be incorporated into the results, thus avoiding unnecessary duplication of effort and testing (see Integrating Rapid with CoPS or LASS for further information about this).
