The Met in London has announced it will start offering training from November, as it aims to attract more women.
All new constable recruits will be able to choose between full-time or part-time working hours.
Christian and recently retired Inspector at Sussex Police, Clare McKnight, worked part time and told Premier: "I think it's extremely good news.
"I think it will absolutely benefit the organisation as a whole and individuals who have got a good skill set that precluded them in the past, due to not being able to give the 40 hours a week.
"When I joined, you had to be full time but in my career, we did move over to part time working for those already in the organisation. So we have made quite a lot of changes over time.
"But I think obviously, this time is now ripe for ensuring that everybody gets that opportunity from the outset."
"Policing is very similar to a lot of our Christian values. We serve the public as we would serve God and hopefully a lot of people will join with this new change in their policy."
The Met hopes the change will make police work more attractive to people with family commitments.
