Yes. You need one qualifying test score (either IQ or achievement) to submit with a portfolio. If it's close, but no cigar, they'll ask you to re-test.

That's what happened to us last year. I submitted the portfolio last year with close, but not qualifying scores. DYS said to re-submit once ds had one qualifying test score. I have plenty of work samples on the pgness, but not a minimum test score yet.
