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.
