August SAT for rising junior?

This is not true. And concerning if you are providing this information to “lots of teens”.

For 2020:

“ AUTHORIZED TEST ADMINISTRATIONS

Only scores earned on administrations of the SAT or ACT from August 2017 through December 2019 will be considered by NMSC. NMSC will not accept scores from a test administration taken earlier than August 2017 or later than December 2019.”

Your score needs to be between the first administration of the year before you took the PSAT to the following December. August Sophomore year to December Senior year.

It’s been roughly +/- 1 year as long as I’ve been following it.
