You don't need to achieve any handicap to turn pro. A 28 handicapper or a +5 can. To become a teaching pro you need to pass a playability test, which is two rounds and you have to shoot under a certain score, it varies from location to location but it is a few over for each round. There are also written tests etc. To be a player, you just need to qualify and try and win your card.
You would not really be able to find out who held the lowest ever golf handicap because it is not really ever released by clubs. Rory McIlroy played of +5 before he turned pro.
Rory McIlroy turned pro in 2007 at the age of 18. His first professional event was the 2007 British Masters where he finished tied for 42nd. In his next event the Alfred Dunhill he finished third and had earned enough to gaurantee a Tour card for the following year (2008 season).
If you want to make the big time like McIlroy, Woods, Mickelson and others, you'd need to be off scratch by 15. But, don't let that deter you, it depends how long you've been playing and your physical development. If you dedicate time to it and practice hard there is no telling what you can achieve. Colin Montgomerie played off 8 when he was 18, and Ian Poulter turned pro with a handicap of 4.
I will assume that you mean a 15 handicap. It depends how long you have been playing for and how old you are. It isn't good enough to turn pro, but it is decent enough in my opinion. It doesn't matter what your handicap is as long as you enjoy the game.
Do you believe in yourself, that you can turn pro when you are 20? 16, is a good handicap for a player who has only been playing for one year, so you clearly have natural ability. If you want to turn pro, you will need to put 6 years very very hard work in. You should consider a good swing coach and plenty of practice.You should also enter as many competitions as you are eligible for, and join as many teams as you can. Down the line you will think of high level amateur events and maybe even college golf. You should not be in any rush to turn pro by 20, a lot of college players wait till 22, 23.The majority of professional golfers reach +3 to +5 before they turn pro.
They would shoot anywhere from a couple of shots over par to a few under par. Tiger Woods played off scratch at 13. Rory McIlroy shot 61 round Royal Portrush at the age of 16, Royal Portush is one of the hardest courses in Northern Ireland and is recognized as one of the best courses in the world.
earn enough experience usually level 30+ and lower your handicap to at least a 70.
Amateurs, regardless of handicap, play the forward tees.
