Key legal question
Whether the insured's hypothetical valid income should be calculated on the basis of a DN II nursing qualification rather than DN I
Extracted holding
The valid income must be set by reference to the average earnings of a nurse with DN I; there were no sufficiently concrete indications that she would have completed DN II absent the accident.
Extracted reasoning
Prior career steps and intentions did not show a sufficiently probable professional advancement to DN II. DN I is a fully valid nursing qualification, not merely a preliminary stage. The claimant's school difficulties and the lack of concrete steps toward DN II meant the hypothesized career path to DN II was less probable than remaining in the established DN I occupation.
