Many governing body programmes deliver regulated qualifications; meaning they meet an agreed set of standards.
Each sport's programme varies, depending on the nature of the sport. For example, face-to-face ‘classroom’ element of a Level 1 course can take from two to four days to complete, with added time for assessment, putting your learning into practice and gaining experience. The cost and length of courses differs from sport to sport too.
You don't need a formal qualification to assist another coach in a club so don't let that stop you getting involved. Qualifications are not required to start your coaching journey. Look out for voluntary roles in your local clubs, hubs and Active Schools teams or search for volunteer positions.
