SAT scores question

Please excuse my ignorance but this is the first time I am dealing with SATs and scores. My rising senior will be taking the test this coming Saturday but already took it once last March. Do we pick which scores we’d send to the schools or do both results (from both dates) get sent?

Each University will state on their website if they require all scores to be sent, if they superscore (taking the best score from each section from multiple sittings) or will take the highest score from a single sitting.

If you send the free score reports when your register, then all scores (including March) are automatically sent. However, you can pay $12 per school and use score choice. In that case, you can choose any or all scores to any university. @Gumbymom is right that you should check each school’s policy. You can change which colleges receive the free score reports until September 4th.

Thank you @Gumbymom and @kimclan1
