hi quarto,
i am an examiner in jaaland and so, not terribly familiar with your requirements but essentially i think they are not a lot different since JAR/FCL seems to apply...
the answer is yes..the skills test is essentially the same as the PPL initial test...with one or two exceptions...for instance..i generally would not do a full cross country again with someone who held a PPL previously...but that would depend on hjow long they had it and how mayn hours they had previously done of x/c flying. mind you, if i fould that they then failed or got a partial pass then on the next occasion i would include a x/c as part of the test..
i think you can google JAA regs.
hope thats of some help but i suppose you better wait for someone mor familiar with your flight testing to answer.
good luck wityh the LST.
the dean.
