On the subject of the SD+D assessment stating that input should be validated, I have had candidates in the past implement validation for Pack 3 Outcome 2 using a restricted choice ‘drop down menu’ (aka. comboBox in VB) rather than the traditional (and IMO old-hat, stuck in the 1980’s) command-line and conditional loop method we all recognise as the ‘standard algorithm’.
I allowed it as by the wording of the Assessment Standards/Making Assessment Judgements, our traditional input validation algorithm is not specifically asked for (even though it is implemented – incorrectly I may add – in the sample solution).
I am glad that my intepretation has been confirmed!
