No. There are two things you need to measure, ability and determination, the first you can test for the second can only really be shown by a track record. Abi

No. There are two things you need to measure, ability and determination, the first you can test for the second can only really be shown by a track record. Ability is very task specific, so what you test for will need to depend on what sort of potential you're looking for. For example for programming a number of studies have shown one of the strongest indicator of being able to program is the ability to form a consistent mental model of how something works (which you can test for without someone having programming experience).
