It is my understanding that if you use the portfolio instead of one of the tests, you need to get the missing test done within the next 6 months. You were also required to submit all the test the child has taken regardless of the outcome. I can't find it on their web page right now though.

We used the scores only so I have no personal experience with this. I think the bottom line is that it's much easier to apply with valid scores than the portfolio. There are also applicants who were asked to submit portfolio as an addition to their valid scores.
