After consultation with EBU clubs last year, changes to the National Grading Scheme are now in effect.
1. The grade of players with "mature" grades will not change when they play with partners who have played fewer than 150 graded boards. The sesion will not count towards the grade of the more experienced player, but will count towards the grade of the less experienced player. It is hoped that this will stop people being deterred from acting as ahost or mentor at their club due to concerns they have about how it might affect their NGS.
2. Grades will be published once you have played 150 boards (previously 300) but they will change more quickly than before to enable new players to reach an appropriate grade sooner. A grade will still be considered "evolving" until you have played 1000 boards, at which point it "matures".
