Saturday's event at the Providence Career and Technical Academy will draw representatives from 41 city and district charter schools.
Families of incoming kindergarteners, sixth-graders and ninth-graders can request their top choices for schools for the 2019-2020 academic year that begins this fall.
Although at least 20 percent of public school seats are reserved for children who live in a given school's neighborhood, families interested in other schools can place their names in a lottery.
Organizers say more than 500 people are expected to participate.
Officials also will present the city's five-year vision for improving schools.
