You may be able to join a club's academy or centre of excellence development programme, if you can show you have the potential to play at a high level.
Academies hold trials during the year and have scouts watching male and female players of all ages. Programmes usually operate from under 10s to under 16s level.
If an academy takes you on, they'll ask you and your parents or guardians to sign forms, which may be renewed every 1 to 2 years. At age 16, the club will decide whether to put you on its youth training scheme. You'll be expected to continue with your education at the same.
You can be offered a professional contract from age 17. If the contract ends, you'll be released into a central pool of players for other clubs to offer you a trial. Some of these clubs may be at a lower level than the one you've been with.
England youth, men's and women's coaches have close links with club development programmes. They constantly watch players of all ages to identify the ones they think have the potential to go on and play for England at senior level.
Contact your local county football association for details of how to get involved in football, and for clubs and development programmes in your area.
