SAT score report - does it include all tests?

My son took the SAT in August with no prep. He didn’t send free score reports to any schools at the time because we didn’t know how well he’d do, and his ACT scores were good, so he figured he’d most likely use those. He ended up with a 1550 on the SAT, so now he wants to use the score.
He is signed up to take two SAT subject tests this Saturday. If he asks for the free score reports to be sent, will the score report include the SAT score from August as part of the report, or just the results of the subject tests?

Yes, it includes SAT and SAT2 scores by default.

It will include the results from the most recent sitting, plus all SAT and/or Subject Test scores from prior sittings.

A note of caution: You may not want to send the subject tests to all schools. A strong SAT score does not guarantee a strong subject test score. Many schools do not require subject tests and you may want to see the score before sending to those that will “consider” but do not require. For those who require scores, but do not require all scores to be sent, your son may want the option of taking the subject test again to improve his score and then send only that score. Not sure if it is too late to change after the test date - that’s probably another thread on CC. For SAT and Subject tests - best to only send free reports to schools that require all scores to be sent anyway.

If you wish to use your free score reports for October, they will necessarily include the results from October, plus you can customize your report to include all, some, or none of previously taken tests. You can report a different subset of results for each school.

For any previous SAT test result, you get to choose for each date whether to include that result. In other words, you have to report the EBRW plus Math plus Essay, if available, for that date. For any previous Subject Test result, you get to choose for each date and each subject test taken on that date whether to include that result. It’s easy for you to experiment: just start the process online to some arbitrary school; you can make changes or cancel the process until Oct. 16.
