Read the Instructions. The most important part of trying out for a reality show is to make sure that you read all the instructions first. These will go over the rules requirements for you to follow. Since a lot of people will mess this simple step up - make sure you've read EVERYTHING and follow it correctly. This will ensure your application doesn't even get picked off before being read.
Practice, Practice, Practice. If you are aiming for a reality show that requires talent, like American Idol or America`s Next Top Model, then you need to start practicing now. Learn that song by heart and work out all the kinks before the audition. Strut your stuff up and down your living room until you have the diva walk down. Previous episodes of the reality show will give you pointers on how you can improve. We have all seen the mishaps people make on television now. It's become quite entertaining to watch people make those mistakes. Don't be one of those people!!
Prepare for it!! Prep yourself. This might sound like the above step however, there is a difference. While practice might make perfect, you will find that some reality shows like Project Runway, will require you to have things prepared. For example, you`ll need to have some very well made garments ready to show the judges if you`re going to be trying out for Project Runway! As for game shows, brush up on your trivia, knowledge, and skill before attempting to try out.
Make a professional yet awesome application video. How might you do that, you ask? Most reality shows require you to send in an application video before you will even be considered for an audition. Don`t be boring. If you just stand there and don't move and just talk or sing, chances are you`ll be eliminated before you even get a actual audition.
Be creative. The best videos are ones that are unique and NOT cliche. This might be difficult but if you are serious about getting on the reality show, then you can put in the effort and time required to come up a great video idea. Keep it clean! Remember, it isn't a youtube video.
Above all, and the most important thing to remember is - confidence. Judges are more likely to pick someone who truly believes in their self. Stand tall, smile, be friendly and know that you "got it in the bag."
