Nell Ashworth, 21, is from King's Lynn and studies social policy at the University of York
As the daughter of a nurse, the virtues of public service were something Nell Ashworth grew up with.
"I basically chose to do my degree in social policy because I want to work for the civil service," she tells us. "I've done all of this preparation for, I suppose, not very much reward."
Nell is all too aware that those who perform well during the summer internship, which typically takes place between the second and third year of a university course, can be fast-tracked into a graduate job in the civil service.
The Fast Stream is the service's flagship programme for recruiting graduates who are trained for leadership and management roles.
It is highly competitive and there were more than 44,000 applications last year, according to government figures, but only 986 were recommended for appointment. Of these, 211 were from lower socio-economic backgrounds.
Overall, there were about 540,000 people working across the civil service as of March 2024.
Under the new rules, Nell would still be allowed to apply for the Fast Stream but not the summer internship programme. This is because eligibility is decided by the jobs an applicant's parents did when they were 14. In Nell's case her mother was a nurse and her father a town planner.
The criteria now being used for the internships are set out by the Social Mobility Commission, an independent body which advises the government.
They categorise jobs into five groups; the lowest two of which are considered working class and include occupations such as mechanic, electrician, shop assistant, labourer, cleaner and waiter.
However, jobs like clerical worker, roofer and taxi driver are considered above these working glass groups, as are public sector jobs like nurses and teachers.
"Mostly, I felt deflated," Nell says of her reaction to seeing the changes, having planned to apply for next year's programme. "If I'd have known then I could have changed my plans and applied for this summer's internship instead."
State school-educated Nell, whose parents were the first in their families to go to university, says she understands why the government is trying to encourage more people with working class backgrounds into the civil service.
Though she considers herself to be one of them and fears others like her will also be dissuaded from working in the public sector as they are not considered working class enough.
"There's me in the middle, not rich or poor, so where do I go? And then that puts me off working in the civil service because now I have no idea who's looking out for me."
