Block, whose late father Ken built up a huge following for his viral Gymkhana videos, will make her single-seater debut with the ART Grand Prix team as the all-female series forges closer ties with F1.
All 10 F1 teams will have a nominated driver in F1 Academy running in its colours in 2024, with Block becoming the second driver to be linked to an F1 outfit.
McLaren announced that Bianca Bustamante would join its driver development programme for her second year, switching from Prema to ART.
Block said: "I am so excited to be joining the Williams Driver Academy and competing in F1 Academy in 2024!
"This is something I never could have dreamed of. I can’t wait to embrace this new experience and learn as much as possible."
Block began competing in national level rallying in 2021, and won the Open Two-Wheel Drive class in the American Rally Association Championship.
She has also contested four rounds of the Extreme E championship alongside Timo Scheider for Carl Cox Motorsport, claiming a best result of fifth in Sardinia, and entered the US-based Nitrocross NEXT series.
