An old case, but basically a complete discussion on what is extraordinary, and it is a court of appeal decision too.

27 Following the Moss approach, an expense for an extracurricular activity is extraordinary only where it is out of proportion to the usual costs associated with that particular activity. For example, if the average costs of downhill skis is $500.00, then $500.00 for downhill skis would not be an extraordinary expense, but $1000.00 would be. The judge would still be required to apply the tests of necessity and reasonableness before determining that the payor should contribute to the extraordinary portion of this expense, but the initial determination of the extraordinary character of the expense would not involve consideration of the payor's means.
