The school is the first college in Los Angeles County to implement a second year of free tuition for students.
Officials announced the expansion of the "Rio Promise" program.
The program began in the 2017-2018 school year, with 456 first-year students from local public high schools participating.
An estimated 443 students will qualify for the second-year program.
The free tuition is for two years.
The Rio Promise is funded by donations and by leveraging Pell grants, California Promise grants and California Promise waivers.
