Susie Wolff will contest two practice sessions for Williams in 2014.
The British team announced on Monday that the 31-year-old's development role has been "expanded" for the new season, and now involves participation in two Friday morning sessions.
Wolff, whose husband Toto is the Mercedes team chief, will also drive the new Mercedes-powered FW36 over a full test day, Grove based Williams added.
"This season will be a big step," said the Scottish driver. "It's a challenge that I will relish and it will be a great chance for me to continue assisting the team."
The last woman to take part in an official grand prix weekend was Italian Giovanna Amati, who failed to qualify three times for Brabham in 1992.
