No the insurance will remain valid. What the policy states is that any new coach that wishes to coach independently (i.e. be responsible for a team over a season, take club sessions independently) is required to complete the new 1st4Sport Level 2 Certificate in Coaching Korfball from 1st March 2016. They should not chose the BKA level 2 course as this will no longer be recognised as an appropriate course for future level 2 korfball coaches and therefore insurance will not be granted.
