Hii,
You’ve completed your 10th and 12th  , and  if you're now interested in joining the police department, then yes, you’re eligible for many roles, especially constable posts, which require just a 12th pass qualification in most  states of India. Like in Telangana State Level Police Recruitment Board (TSLPRB) or Andhra Pradesh State Police, they conduct exams for:Police Constable (Civil, AR, etc), Warder, and Fireman.
Here you can do :
1. Keep tracking the official state police recruitment websites.
2. Check for announcements on Constable Recruitment – notifications are usually out every 1–2 years.
3. First you will need to clear:A Preliminary Written Test, then a physical efficiency Test (PET) running, etc, Main written exam
All the best,
Thank you!
