First, you need to figure out what is your goal as a video game tester. Do you
want to become one so you can get your foot in the door of the game company?
Figure out what you want before you dive in.
I highly recommend that you have a college degree. The most desirable ones are
business related, designs, and programming. A college degree would help you move
up in the company faster, and perhaps start you off in a better position.
If all you want to do is be a video game tester, then a high school diploma
should do the trick. You will start off at a low wage, and will increase as you
show efforts to become a really good video game tester.
What you really need to qualify:
You must have writing skills. They have to be very clear and concise. You cannot
write, "I think this game is fun." They are not hiring 2nd graders here. You
need to be serious, and you need to write like an adult. You have to give
in-depth details, such as bugs, crashes, etc.
It is not always writing that matters because you will also need verbal skills.
Telephone communication might be necessary from time to time. If no one
understand what you are saying over the phone, you are going to have a lot of
trouble as a video game tester.
You also need some computer literacy. I am talking about things such as the
internet, word processing, and know how to make screen shots of the game.
