All but two of the universities in the Russell Group are part of the Sutton Trust's group of 30 highly selective universities, the Sutton Trust 30 (the absent members being Queen Mary University of London and Queen's University Belfast). The Sutton 13 group of the 13 most highly selective universities only includes one non-Russell Group member, the University of St Andrews. The top 10 by average UCAS tariff score of new undergraduate students in 2018–19 included four non-Russell Group universities: St Andrews (2nd; 211 points), Strathclyde (5th; 199 points), Aberdeen (9th; 183 points) and Dundee (10th; 177 points); in 2015–16, using the old UCAS tariff, St Andrews was the only non Russell Group university in the top ten, placed fifth with an average score of 525 (and an offer rate of 52.2%). The average offer rate across 'high tariff' UK institutions (as defined by UCAS) was 73.4% in 2019. Offer rates include conditional and unconditional offers.
