@Dizzywillow What SSP program are you asking about? This one: http://www.ssp.org ? If so, is your student a junior or a senior this year? That SSP is a summer program for juniors to apply to.
If your student is a junior and wants to apply to that SSP, the answer is that all scores are not required. You can list the best ones. And, you can list things like PSAT or AP scores on your application. I would submit more than one type of score to be competitive for SSP.
