CONFIRMED (full version with details and dates below):

LSAC has announced they'll continue offering the LSAT online through June 2022, and they've also released more test dates.

They'll add a 4th experimental section beginning with the August LSAT.

They'll also add a break between sections 2 and 3.

-LSAC announced they'll continue offering the LSAT online through June 2022, but they're not *calling* it LSAT-Flex after June 2021. I'm guessing this is to avoid confusion with the current 3-section format.

-They'll add a 4th section (experimental) beginning with the August LSAT.

-They'll add a break between sections 2 and 3.

-Registration for the August 2021-June 2022 LSAT administrations will open in mid-May 2021.

I've listed all known upcoming test dates below.

The first two were already released.

The ones after this June are listed as "LSAT" because LSAC will simply call it the LSAT starting then, but it'll still be the same as the current LSAT-Flex -- just with the extra section.

February LSAT-Flex will be the week starting February 20

The LSAT will continue to have three scored sections and one unscored experimental for the next several years.
