I normally umpire (done the courses and everything so I must know what I'm doing...)
It was always compulsory as a jumior to learn how to score! When i do score i dont have the neatest book but can say that it is going to add up and be correct.Think all juniors should have to learn, good skill to have!
As a junior I bluntly refused to score every time the book was passed my way in an adult midweek game, I didn't care if they dropped me because I was only doing fine leg to fine leg and batting 11 anyway. They soon stopped passing it to me and a couple of others once the book got five overs behind too many times. My current club has scorers for both teams so we don't have to try and force it on someone, the club secretary regularly wins the best kept scorebook award. Umpiring is a must in second team games though, we have an umpire shortage so normally there's only one league appointed umpire, he/she stands at the non-striker's end at both ends whilst a player from the batting side takes square leg. I often end up stood umpiring for 7-10 overs, I'd rather do that than score any day of the week.
