The Science Education Tracker, 2023 (SET 2023) is the third survey in a series of studies which track evidence on key indicators for science engagement, education, and career aspirations among young people in England. Although the surveys are part of the same series, the commissioning and funding arrangements for the series have changed over time. The first two surveys were conducted in 2016 (SET 2016) and 2019 (SET 2019), when the survey was known as the Wellcome Science Tracker. The survey series was initially commissioned by Wellcome with support from the Department for Education (DfE), the Royal Society and the (then) Department for Business, Energy & Industrial Strategy (BEIS). Wellcome also commissioned the 2019 survey, which was supported by the Royal Society, DfE, and UK Research and Innovation (UKRI).  For SET 2023, Wellcome provided the Royal Society with a grant to manage the project, who in turn commissioned EngineeringUK to manage the research for the project, and the name of the study is now Science Education Tracker.All surveys since 2016 have been carried out by Verian, formerly known as Kantar Public. The SET 2023 survey covered 7,256 students in school years 7-13 in state funded schools across England, which represents a sample of c.1,000 students per school year. This was based on a similar survey design to SET 2019. As in previous SET surveys, all survey data were collected via an online survey platform. The survey was branded the Pathways Survey in all correspondence with young people.
