Employers will want to see that you have completed a Level 3 course in ICT, like an A level.
You may choose to specialise in a specific IT system (e.g. Microsoft) or in a certain business area. This will require further training. Some employers may offer training or you could go to college to do this. You may specialise in hardware, software, networks, websites or communications, or you may be able to deal with all of them. You will maintain existing systems and equipment. You may also help with designing and installing new systems.
