The powerful winger, who signed for the Exiles two summers ago, once he had graduated from Durham University with a politics degree, will be staying at the RAG for a third year.
Stevenson has had a breakout season this year after struggling in his first season, after picking up a quad injury which kept him on the sidelines for most of last season.
The Old Sedberghian has been a key feature for Scottish this year. He has played 17 times this year scoring 10 tries, including a fine solo effort at Goldington Road against Bedford Blues.
Stevenson has a lot more to offer the Exiles after only making four appearances in his first year of professional rugby but will be aiming to make a big impression this season.
The year before Rob joined the Scots, he was at Durham University and was named in the BUCS Super Rugby Team of the Year for 2016/17 and has also featured for Wales Students and GB Students in the World University 7s Championships two years ago.
