‘VDW Credits’ can only be awarded for a maximum of 5 years. Different periods of work as a VDW are aggregated for the purpose of calculating the 5 years. For example, if you were a VDW for three years previously, and wish to go abroad as a VDW for another three years, you will only qualify for ‘VDW Credits’ for two years of your second assignment.
Where the period of your assignment abroad exceeds 5 years, you will, where possible, be awarded ‘VDW Credits’ for the period that is most beneficial to you.
