Until 2023 the number of mandates allocated in proportional and majoritarian parts were standing at 30 each.

Seats in the proportional part are allocated using the Imperiali quota, modified to ensure that every party list, which passes the threshold, receives at least one mandate.

The following parties were relieved from the necessity to collect signatures:[2] New People will take part in Rostov Oblast legislative election for the first time, while Party of Pensioners of Russia and People's Alliance, who took part in the last legislative election, had been dissolved prior.

40 single-mandate constituencies were formed in Rostov Oblast, an increase of 10 seats since last redistricting in 2018.

Aleksandr Ischenko (United Russia) was re-elected as Chairman of the Legislative Assembly, while Senator Irina Rukavishnikova (United Russia / Independent) was re-appointed to the Federation Council.
