I applied for the police. You don't have to have any specific qualifications although it helps to have some GCSE's. You have to sit tests and go to situational interviews and pass medical and fitness tests. It took over a year for me to complete the whole process. If you go on to Amazon you can buy books which help you through the exams and interviews. You don't do your training until you have passed everything and have been accepted
im 15, and i want to join the police too :) you dont have to have any qualifications at all but if you do it would probably help. When you train you get sent to a poice training school to learn everything you need to, so you dont have to worry about that. it takes a while to get in so keep trying and if you get in straight away then pat yourself on your back lol
